drm/amdgpu: Rework VMID reservation logic

Browse source 
Rework the VMID reservation logic by passing in the mask
of VMIDs (for both GFXHUB and MMHUB) available for it to
use. The VMID masks for both GFXHUB and MMHUB are initialized
in the respective ASIC specific files.
This also helps in reserving per-ASIC VMIDs. This is in
preparation for reserving a VMID for NPA added in the next
patch.
