drm/amdgpu: Add DCC GFX12 flag to enable address alignment
We require this flag AMDGPU_GEM_CREATE_GFX12_DCC or any other
kernel level GFX12 DCC flag to differentiate the DCC buffers and other
pinned display buffers(which has TTM_PL_FLAG_CONTIGUOUS enabled).
If we use the TTM_PL_FLAG_CONTIGUOUS flag for DCC buffers, we may over
allocate for all the pinned display buffers unnecessarily that leads to
memory allocation failure.
