Now that we have hooks to enable the atomic plane helpers, we can use the plane helpers for our .update_plane() and .disable_plane() entrypoints.
Even though we'd already refactored our plane handling code into check/commit, we still have to rework some of that logic here as we make the transition. The atomic plane helpers now call prepare_fb/cleanup_fb for us, so note the following: - 'commit' should no longer unpin the old object; the cleanup_fb will take care of this for us - prepare_fb only gets called when we actually have an fb, so the internal 'disable' code needs to update frontbuffer tracking - the cursor plane code never had 'prepare' code separated from its 'commit' function, so a lot of the cursor's 'commit' needs to be dropped since prepare_fb already does it for us - with all the pinning work removed from cursor commit, it can no longer fail and should return void rather than int
