OMAP: DSS2: Remove support for non-DISPC overlays
Remove support for non-DISPC overlays and overlay managers. The support to possibly have non-DISPC overlays and managers was made to make it possible to use CPU and/or sDMA to update RFBI or DSI command mode displays. It is ok to remove the support, because: - No one has used the feature. - Display update without DISPC is very slow, so it is debatable if the update would even be usable. - Removal cleans up code. - If such a feature is needed later, it is better implemented outside omapdss driver.
