From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
We've replicated the fb pin/unpin code in a few places. Pull it into
convenint helpers.
Slight change in locking behaviour as intel_cleanup_plane_fb() now
grab struct_mutex unconditionally.
v2: Change the locking to be symmetric between pin and unpin
