drm/amdgpu: Introduce SRIOV critical regions v2 during VF init
1. Introduced amdgpu_virt_init_critical_region during VF init.
- VFs use init_data_header_offset and init_data_header_size_kb
transmitted via PF2VF mailbox to fetch the offset of
critical regions' offsets/sizes in VRAM and save to
adev->virt.crit_region_offsets and adev->virt.crit_region_sizes_kb.
