drm/amd/amdgpu: cleanup parse_cs callbacks

Because gpu_addr is updated in the calling routine

Use .patch_cs_in_place instead of .parse_cs for
amdgpu_vce_ring_parse_cs_vm() as there is no need for keeping
a temporary IB, therefore ib->sa_bo is NULL and amdgpu_ib_free()

drm/amd/display: 3DLUT non-DMA refactor

[Why]
Currently the handling for 3DLUT is found in multiple different
places, which causes issues when the different functions are not
in sync with each other.
Frequently bugs occur because the LUT handling is broken up, and
what has already been handled isn't kept track of well, which can
cause earlier changes to the LUT params to be overridden.

[How]
Remove DMA LUT handling from DCN401 and refactor legacy LUT
handling in one place to make it easier to keep track of what has
and needs to be done.

drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2)

This commit adds a null check for the 'afb' variable in the
amdgpu_dm_update_cursor function. Previously, 'afb' was assumed to be
null at line 8388, but was used later in the code without a null check.
This could potentially lead to a null pointer dereference.

Changes since v1:
- Moved the null check for 'afb' to the line where 'afb' is used. (Alex)

Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:8433 amdgpu_dm_update_cursor()
error: we previously assumed 'afb' could be null (see line 8388)

v2:
  - adjust size based on the max_texture_channel_caches values
    only for GFX12 DCC buffers.
  - used AMDGPU_GEM_CREATE_GFX12_DCC flag to apply change only
    for DCC buffers.
  - roundup non power of two DCC buffer adjusted size to nearest
    power of two number as the buddy allocator does not support non
    power of two alignments. This applies only to the contiguous
    DCC buffers.

v3:(Alex)
  - rewrite the max texture channel caches comparison code in an
    algorithmic way to determine the alignment size.

v4:(Alex)
  - Move the logic from amdgpu_vram_mgr_dcc_alignment() to gmc_v12_0.c
    and add a new gmc func callback for dcc alignment. If the callback

v5:(Alex)
  - Set the Alignment to a default value if the callback doesn't exist.
  - Add the callback to amdgpu_gmc_funcs.

v6:
  - Fix checkpatch warning reported by Intel CI.

v7:(Christian)
  - remove the AMDGPU_GEM_CREATE_GFX12_DCC flag and keep a flag that

v8:(Christian)
  - move this check into gmc_v12_0_get_dcc_alignment.

v9:

drm/amd/display: Force enable 3DLUT DMA check for dcn401 in DML

[WHY]
Currently TR0 (trip 0) is not properly budgeting for urgent latency in
DML2.1. This results in overly aggressive prefetch schedules that are
vulnerable to request return jitter, resulting in severe underflow at
the start of the frame.

[HOW]
Forcing 3DLUT DMA check to enable causes urgent latency to be budgeted
properly into the prefetch schedule, avoiding the vulnerability.
