drm/amdgpu: update GPU addresses for SMU and PSP
add amdgpu_bo_fb_aper_addr() and update the cached GPU addresses to use
the FB aperture address for SMU and PSP.
2 reasons for this change:
1. when pdb0 is enabled, gpu addr from amdgpu_bo_create_kernel() is GART
aperture address, it is not compatible with SMU and PSP, it need to be
updated to use FB aperture address.
2. Since FB aperture address will change after switching to new GPU
index after hibernation, it need to be updated on resume.
