drm/amdgpu: add gfxhub v2.0 block for navi10 (v4)
gfxhub is the memory controller hub for gfx and sdma.
v1: add place holder and initial basic functions (Ray)
v2: replace the refernce to legacy mc structure with gmc structure
remove the direct use of gart.table_addr (Hawking)
v3: switch to use amdgpu_gmc_pd_addr (Hawking)
v4: squash in updates (Alex)
