drm/amdgpu: GFX12.1 scratch memory limit up to 57-bit
The scratch aperture or gmc private aperture in flat memory contains
57 bits of data on gfx v12.1.0 compared to the 32 bits from previous.
Add new helper kfd_init_apertures_v12 for gfx version >= v12.1.0 which
supports 57-bit VA space.
v2:
- update pdd->scratch_limit (Yu, Lang)
- update fixes tag (Felix Kuehling)
- add helper kfd_init_apertures_v12
