OMAPDSS: RFBI: Use dss_mgr_enable to enable the overlay manager
The RFBI driver uses a direct DISPC register write to enable the overlay manager. Replace this with dss_mgr_enable() which checks if the connected overlay and managers are correctly configured, and configure DSS for fifomerge. Signed-off-by: Archit Taneja <archit@ti.com>
