If the MEC firmware supports chaining runlists of XNACK+/XNACK-
processes, set SQ_CONFIG1 chicken bit and SET_RESOURCES bit 28.

When the MEC/HWS supports it, KFD checks the XNACK+/XNACK- processes mix
happens or not. If it does, enter over-subscription.

Add a callback to check if there is any condition detected by GMC block
for reset on init. One case is if a pending NPS change request is
detected. If reset is done because of NPS switch, refresh NPS info from
discovery table.

If a user has requested NPS mode switch, place the request through PSP
during unload of the driver. For devices which are part of a hive, all
requests are placed together. If one of them fails, revert back to the
current NPS mode.

Add a sysfs interface to see available NPS modes to switch to -

	cat /sys/bus/pci/devices/../available_memory_paritition

Make the current_memory_partition sysfs node read/write for requesting a
new NPS mode. The request is only cached and at a later point a driver
unload/reload is required to switch to the new NPS mode.

Ex:
	echo NPS1 > /sys/bus/pci/devices/../current_memory_paritition
	echo NPS4 > /sys/bus/pci/devices/../current_memory_paritition

The above interfaces will be available only if the SOC supports more than
one NPS mode.

Also modify the current memory partition sysfs logic to be more
generic.

Add address alignment support to the DCC VRAM buffers.

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
    is non-NULL, call it to get the alignment, otherwise, use the default.

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
    checks the BO pinning and for a specific hw generation.

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

v9:
  - Fix 32bit build errors
