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)

[Why]
If disable the mmhub vm contexts(set MMVM_CONTEXTS_DISABLE to 0xffff),
driver loading failed on vf due to fence fallback timer expired on all rings.
FLR cannot reset MMVM_CONTEXTS_DISABLE.
So this vf can not be recovered anymore unless trigger a whole gpu reset.
[How]
Under SRIOV, init MMVM_CONTEXTS_DISABLE in gmc11 golden register setting.

This reverts commit 1a65327a84.
This should be resolved so we can re-enable this. Also,
the AGP apeture was bring programmed to 0 on MMHUB 3.0.1
since agp_start and end were not being set.

[Why]
SDMA0_CNTL and MMHUB system aperture related registers are blocked by L1 Policy.
Therefore, they cannot be accessed by VF and loged in violation.
[How]
For MMHUB registers, they will be programmed by PF. So VF will skip to program them in mmhubv3_0.
For SDMA0_CNTL which is a PF_only register, VF don't need to program it in sdma_v6_0.

Rename vram_scratch into mem_scratch and allow allocating it into GTT as
well.
The only problem with that is that we won't have a default page for the
system aperture any more.

MES firmware needs the setting of VM_CONTEXT_CNTL to perform
vmid switch. Save the initial setting when hub initializing.
