drm/omap: Call dispc timings check operation directly 

Instead of call the dispc timings check function dispc_mgr_timings_ok()
from the internal encoders .check_timings() operation, expose it through
the dispc ops (after renaming it to check_timings) and call it directly
from omapdrm. This allows removal of now empty omap_dss_device
.check_timings() operations.
