drm/omap: Add a dss device operation flag for .get_modes()
Instead of manually iterating over the dss devices in the pipeline to
find the first one that implements the .get_modes() operation, add a new
operation flag for .get_modes() and use the omap_connector_find_device()
helper function to locate the right dss device.
