From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
To avoid having to deference plane_state->vma during the commit phase of
plane updates, let's store the vma gtt offset (or the bus address when
we need it) in the plane state. This is crucial for doing the modeset
operations during GPU reset as as plane_state->vma gets cleared when we
duplicate the state and we won't be calling .prepare_fb() during GPU
reset plane commits.
