889fcbe949 drm/nouveau/disp: add common channel class handling
Replaces a bunch of unnecessarily duplicated boilerplate in per-chipset
code with a simpler, common, implementation.

Channel "awaken" notify code is completely gone for now.  KMS has never
made use of it so far, and event notify handling is about to be changed
in general anyway.

acbe9ecfb7 drm/nouveau/disp: merge head/outp/ior code into chipset files
No changes to code at all here, just shuffling it around and removing
a bunch of (now unnecessary) forward-declarations from headers.

168c029943 drm/nouveau/disp: add common class handling between <nv50 and >=nv50
About to expose head/output path/connector objects everywhere, so we will
need support for child classes prior to nv50 now.

Somewhat cleaner than the code >=nv50 used previously.

v2:
- use ?: (lyude)

Dump of one struct's members into another, with a couple of list

0407b33fad drm/nouveau/disp: collapse nv50_disp_func into nvkm_disp_func
Aside from a chicken-and-egg problem with a duplicate 'root' member,
this is a straight dump of function pointers from one struct into
another.

The left-over wrapping mess in >=nv50 structs will be fixed later.

bb3b0a4220 drm/nouveau/disp/nv50-: initialise from the engine, rather than the user object
Engines are initialised on an as-needed basis, so this results in the
same behaviour, whilst allowing us to simplify things a bit.

6c22ea3747 drm/nouveau/disp: introduce acquire/release display path methods
These exist to give NVKM information on the set of display paths that
the DD needs to be active at any given time.

Previously, the supervisor attempted to determine this solely from OR
state, but there's a few configurations where this information on its
own isn't enough to determine the specific display paths in question:

- ANX9805, where the PIOR protocol for both DP and TMDS is TMDS.
- On a device using DCB Switched Outputs.
- On GM20x and newer, with a crossbar between the SOR and macro links.

After this commit, the DD tells NVKM *exactly* which display path it's
attempting a modeset on.

78f1ad6f65 drm/nouveau/disp: introduce input/output resource abstraction
In order to properly support the SOR -> SOR + pad macro separation
that occurred with GM20x GPUs, we need to separate OR handling out
of the output path code.

This will be used as the base to support ORs (DAC, SOR, PIOR).
