15d3f14f36 drm/i915/gvt: use macros from drm_dp.h instead of duplication
Use the existing macros in drm_dp.h for DPCD and DP AUX instead of
duplicating. Remove unused macros, as well as the duplicate definition
of DPCD_SIZE.

AUX_NATIVE_REPLY_NAK is left unchanged, as it does not match
DP_AUX_NATIVE_REPLY_NACK, and I'm not sure what the right thing to do is
here.

bc3ca4d943 drm/i915: Make I2C terminology more inclusive
I2C v7, SMBus 3.2, and I3C 1.1.1 specifications have replaced "master/slave"
with more appropriate terms. Inspired by Wolfram's series to fix drivers/i2c/,
fix the terminology for users of I2C_ALGOBIT bitbanging interface, now that
the approved verbiage exists in the specification.

ab11a9270a drm/i915: make more headers self-contained
The headers in the gem/selftests/, gt/selftests, gvt/, selftests/
directories have never been compile-tested, but it would be possible
to make them self-contained.

This commit only addresses missing <linux/types.h> and forward
struct declarations.

ee145f66e7 drm/i915/gvt: Fix static checker warning on intel_gvt_i2c_handle_aux_ch_write()
Static checker gave warning on:

drivers/gpu/drm/i915/gvt/edid.c:506 intel_gvt_i2c_handle_aux_ch_write()
warn: odd binop '0x0 & 0xff'

We try to return ACK for I2C reply which is defined with 0. Remove
bit shift which caused misleading bit op.

It consists a collection of display MMIO handlers, like power well register
handler, pipe register handler, plane register handler, which will emulate
all display MMIOs behavior to support virtual mode setting sequence for
guest.
