drm/amd/display: Add wrapper to call planes and stream update

drm/amd/display: Use dc_update_planes_and_stream

drm/amd/display: Add minimal pipe split transition state
Just as a heads-up, the above patches result in UI failures when booting
chromeos-5.15 on a Stoney GPU. I don't know if that is because of other
ChromeOS specific backports into chromeos-5.15, so there may be no problem
with linux-5.15.y. I just wanted to report it in case others observe a
similar problem. For reference, the warning traceback observed with
chromeos-5.15 is attached below.
Reverting the above patches fixes the problem for us.
