Apply this rule to all newer asics in sriov case.
For asic with VF MMIO access protection avoid using CPU for VM table updates.
CPU pagetable updates have issues with HDP flush as VF MMIO access protection
blocks write to BIF_BX_DEV0_EPF0_VF0_HDP_MEM_COHERENCY_FLUSH_CNTL register
during sriov runtime.
Moved the check to amdgpu_device_init() to ensure it is done after
amdgpu_device_ip_early_init() where the IP versions are discovered.

if reading pf2vf data failed 30 times continuously, it means something is
wrong. Need to trigger flr_work to recover the issue.

also use dev_err to print the error message to get which device has
issue and add warning message if waiting IDH_FLR_NOTIFICATION_CMPL
timeout.

This should be changed to also check scratch_reg1 for any errors

It's used for more than just SR-IOV now, so move it to
amdgpu_gmc.c and rename it to better match the functionality and
update the comments in the code paths to better document
when each path is used and why.  No functional change.

<title>drm/amdgpu: Use correct KIQ MEC engine for gfx9.4.3 (v5)</title>

amdgpu_kiq_wreg/rreg is hardcoded to use MEC engine 0.

Add an xcc_id parameter to amdgpu_kiq_wreg/rreg, define W/RREG32_XCC
and amdgpu_device_xcc_wreg/rreg to use the new xcc_id parameter.

Using amdgpu_sriov_runtime to determine whether to access via kiq or
RLC is sufficient for now.

v5: add condition in amdgpu_device_xcc_w/rreg, remove trace func call

v4: avoid using amdgpu_sriov_w/rreg

v3: use W/RREG32_XCC to handle non-kiq case

v2: define amdgpu_device_xcc_wreg/rreg instead of changing parameters
