Laurent Pinchart d46a4e93ea drm: rcar-du: vsp: Extract framebuffer (un)mapping to separate functions
The rcar_du_vsp_plane_prepare_fb() and rcar_du_vsp_plane_cleanup_fb()
functions implement the DRM plane .prepare_fb() and .cleanup_fb()
operations. They map and unmap the framebuffer to/from the VSP
internally, which will be useful to implement writeback support. Split
the mapping and unmapping out to separate functions.
