drm/amdgpu: Add EXT_COHERENT support for APU and NUMA systems
On gfx943 APU, EXT_COHERENT should give MTYPE_CC for local and
MTYPE_UC for nonlocal memory.
On NUMA systems, local memory gets the local mtype, set by an
override callback. If EXT_COHERENT is set, memory will be set as
MTYPE_UC by default, with local memory MTYPE_CC.
Add an option in the override function for this case, and
add a check to ensure it is not used on UNCACHED memory.
V2: Combined APU and NUMA code into one patch
V3: Fixed a potential nullptr in amdgpu_vm_bo_update
