OMAPDSS: APPLY: move mgr->enabled to mgr_priv_data
struct omap_overlay_manager contains "enabled"-field, used to track if the manager is enabled or not. This field should be internal to apply.c. This patch moves the field to mgr_priv_data, and applies the necessary locking when accessing the field. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
