drm/amdgpu: Add logic for VF ipd and VF bios to init from dynamic crit_region offsets

Browse Source 
1. Added VF logic in amdgpu_virt to init IP discovery using the offsets from dynamic(v2) critical regions;
2. Added VF logic in amdgpu_virt to init bios image using the offsets from dynamic(v2) critical regions;
