[PATCH 2/9] drm/xe/vf: Don't run any save-restore RTP actions if VF

There are no RTP save-restore actions applicable for VFs on
current platforms. If any future platform will require some,
we will need to update the RTP framework to support VF_READY
or VF_ONLY actions. In the meantime, just skip all actions if
we are running as VF driver.
