drm/amdgpu: Add early fini callback
Use it to call disply code dependent on device->drv_data
before it's set to NULL on device unplug
v5:
Move HW finilization into this callback to prevent MMIO accesses
post cpi remove.
v7:
Split kfd suspend from device exit to expdite HW related
stuff to amdgpu_pci_remove
v8:
Squash previous KFD commit into this commit to avoid compile break.
