Set the mode_changed field on the crtc_states and use that instead.
Note that even though this patch doesn't completely replace the logic in
intel_modeset_affected_pipes(), that logic was never fully used to its
full extent. Since the commit mentioned below, modeset_pipes and
prepare_pipes would only contain at most the pipe for which the set_crtc
ioctl was called. We can grow back that logic when the time comes.

Since universal planes the primary plane might not be around, and it's
kinda silly to restrict the pipe bpp to the primary plane if we might
end up displaying a 10bpc video overlay. And with atomic we might very
well enable a pipe without a primary plane. So just use the platform
max as a starting point and then restrict appropriately.
Of course this is all still a bit moot as long as we artificially
compress everything to max 8bpc because we don't use the hi-bpc gamma
tables.

Note that the CDCLK initialization/uninitialization are done at their
current place only for simplicity, in a future patch - when more of the
runtime PM features will be enabled - these will be moved to power
well#1 and modeset encoder enabling/disabling hooks respectively. This
also means that atm dynamic power gating power well #1 is effectively
disabled.
The call to uninitialize CDCLK during system/runtime suspend will be
added later in this patchset.
v1: Added function definitions in header files

- Moved CDCLK related definitions to i915_reg.h
- Removed defintions for CDCLK frequency
- Split uninit_cdclk() by adding a phy_uninit function
- Calculate freq and decimal based on input frequency
- Program SSA precharge based on input frequency
- Use wait_for 1ms instead 200us udelay for DE PLL locking
- Removed initial value for divider, freq, decimal, ratio.
- Replaced polling loops with wait_for
- Parameterized latency optim setting
- Fix the parts where DE PLL has to be disabled.
- Call CDCLK selection from mode set
v3: (imre)
- add note about the plan to move the cdclk/phy init to a better place
- take rps.hw_lock around pcode access
- move DE PLL register macros here from another patch since they are

- add BXT_ prefix to CDCLK flags
- add missing masking when programming CDCLK_FREQ_DECIMAL
v4: (ville)
- split the CDCLK/PHY parts into two patches, update commit message
accordingly
- s/DISPLAY_PCU_CONTROL/HSW_PCODE_DE_WRITE_FREQ_REQ/
- simplify BXT_DE_PLL_RATIO macros
- fix BXT_DE_PLL_RATIO_MASK
- s/bxt_select_cdclk_freq/broxton_set_cdclk_freq/
- move cdclk init/uninit/set code from intel_ddi.c to intel_display.c
- remove redundant code comments for broxton_set_cdclk_freq()
- sanitize fixed point<->integer frequency value conversion
- use DRM_ERROR instead of WARN
- do RMW when programming BXT_DE_PLL_CTL for safety
- add note about PLL lock timeout being exactly 200us
- make PCU error messages more descriptive
- instead of using 0 freq to mean PLL off/bypass freq use 19200
for clarity, as the latter one is the actual rate
- simplify pcode programming, removing duplicated
sandybridge_pcode_write() call
- sanitize code flow, remove unnecessary scratch vars in
broxton_set_cdclk() (imre)
- Remove bound check for maxmimum freq to match current code.
This check will be added later at a more proper platform
independent place once atomic support lands.
- add note to remove freq guard band which isn't needed on BXT
- add note to reduce freq to minimum if no pipe is enabled
- combine broxton_modeset_global_pipes() with

Added intel_atomic_setup_scalers to setup scalers based on
staged scaling requests from a crtc and its planes. If staged
requests are supportable, this function assigns scalers to
requested planes and crtc. Note that the scaler assignement
itself is staged into crtc_state and respective plane_states
for later commit after all checks have been done.
overall high level flow:
- scaler requests are staged into crtc_state by planes/crtc
- check whether staged scaling requests can be supported
- add planes using scalers that aren't in current transaction
- assign scalers to requested users
- as part of plane commit, scalers will be committed
(i.e., either attached or detached) to respective planes in hw
- as part of crtc_commit, scaler will be either attached or detached
to crtc in hw
crtc_compute_config calls intel_atomic_setup_scalers() to start
scaler assignments as per scaler state in crtc config. This call
should be moved to atomic crtc once it is available.

Switch from our plane update/disable entrypoints to use the full atomic
helpers (which generate a top-level atomic transaction) rather than the
transitional helpers (which only create/manipulate orphaned plane states
independent of a top-level transaction). Various upcoming work (SKL
scalers, atomic watermarks, etc.) requires a full atomic transaction to
behave properly/cleanly.
Last time we tried this, we had to back out the change because we still
call the drm_plane vfuncs directly from within our legacy modesetting
code. This potentially results in nested atomic transactions, locking
collisions, and other failures. To avoid that problem again, we
sidestep the issue by calling the transitional helpers directly (rather
than through a vfunc) when we're nested inside of other legacy
modesetting code. However this does allow legacy SetPlane() ioctl's to
process an entire drm_atomic_state transaction, which is important for
upcoming patches.

If we hit a vblank and see that have a pageflip queue but not yet
processed, ensure that the GPU is running at maximum in order to clear
the backlog. Pageflips are only queued for the following vblank, if we
miss it, there will be a visible stutter. Boosting the GPU frequency
doesn't prevent us from missing the target vblank, but it should help
the subsequent frames hitting theirs.
v2: Reorder vblank vs flip-complete so that we only check for a missed
flip after processing the completion events, and avoid spurious boosts.
v3: Rename missed_vblank
v4: Rebase
v5: Cancel the outstanding work in runtime suspend
v6: Rebase
v7: Rebase required fixing

Currently we emit semaphore synchronisation as if we were going to flip
using the target CS engine, but we then change our minds and do the flip
using the CPU. Consequently we write instructions to the ring but never
use them - even to the point of filling that ring up entirely and never
submitting a request.
The wrinkle in the ointment is that we have to tell a white lie to
pin-to-display for it to skip the synchronisation for mmioflips as we
will create a task specifically for that slow synchronisation. An oddity
of note is the discrepancy in requests that we tell to pin-display to
serialise to and that we then eventually wait upon. This is due to a
limitation in the i915_gem_object_sync() routine that will be lifted
later.

Reduce dependency on the staged config by using the atomic state
instead.

It's not needed anymore, now that all the users were converted to using
an atomic state.
