writeback is a like DPI in the sense that it's completelty a part of DISPC.
Hence it doesn't have it's own resource, or a hwmod entity tied to it.
Create a simple platfrom device for writeback in omap_display_init. Set the
parent to the omapdss_dss platform device like done for other DSS submodules.
