drm/amdgpu: introduce vmhub definition for multi-partition cases (v3)
v1: Each partition has its own gfxhub or mmhub. adjust
the num of MAX_VMHUBS and the GFXHUB/MMHUB layout (Le)
v2: re-design the AMDGPU_GFXHUB/AMDGPU_MMHUB layout (Le)
v3: apply the gfxhub/mmhub layout to new IPs (Hawking)
v4: fix up gmc11 (Alex)
v5: rebase (Alex)
