From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>
Merge it into the plane update_plane() callback and make other
users use the update_plane() functions instead.
The fb != crtc->cursor->fb was already inside intel_crtc_cursor_set_obj()
so we fold intel_crtc_cursor_set_obj() inside intel_commit_cursor_plane()
and merge both paths into one.
v5 (by Matt):
- Rebase onto latest di-nightly codebase
- Drop extra unreference call when we fail to pin (Ville)
