drm/nouveau/kms/nv50-: implement proper push buffer control logic
We had a, what was supposed to be temporary, hack in the KMS code where we'd
completely drain an EVO/NVD channel's push buffer when wrapping to the start
again, instead of treating it as a ring buffer.

drm/nouveau/kms/nv50-: wrap existing command submission in nvif_push interface
This commit pulls in a bunch of new push buffer macros which are able to
support NVIDIA's class headers, and provide more useful debug output and
error checking (compile-time, where possible) than we had previously.
Will incrementally transition each function over to the unified interfaces.

drm/nouveau: Use fallthrough pseudo-keyword
Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.
The nvif_object_ioctl() method NVIF_VMM_V0_PFNMAP wasn't correctly
setting the hardware specific GPU page table entries for 2MB sized
pages. Fix this by adding functions to set and clear PD0 GPU page
table entries.

It technically loads, and runs, but is ultimately pointless outside of
a very narrow window (fanless systems where one wants to attempt using
the, broken for a lot of gm20x, memory reclocking code).
It's also potentially dangerous to override the VBIOS-provided "Pre-OS"

drm/nouveau/acr: store a mask of LS falcons the controlling LSFW can bootstrap
This will prevent some pain with broken firmware trees, as under some
circumstances the HSFW can fail and leave the GPU in a state we don't
know how to recover from.
This causes us to invalidate MMU only at the level we made modifications -
ie: if we've only modified PTEs, there's no need to have MMU dump the PDs
it's fetched into L2.

nvkm_timer_wait_init() takes a u64 as a duration parameter, but the
expression "(m) * 1000" will be promoted only to a 32-bit integer,
if 'm' is also an integer. Changing the 1000 to 1000ULL ensures that
the expression will be 64 bits.
This change currently has no effect as there are no callers of
nvkm_msec() that exceed 2000ms.

This set of patches contains a few preparatory patches to enable video
capture support from external camera modules. This is a dependency for
the V4L2 driver patches that will likely be merged in v5.9 or v5.10.
On top of that there are a couple of fixes across the board as well as

From a feature point of view this also adds support for horizontal
