drm/omap: Expose DRM modes instead of timings in display devices
omap_dss_device operations expose fixed video timings through a .get_timings() operation that return a single timing for the device. To prepare for the move to drm_bridge, modify the API to instead add DRM modes directly to the connector. As this puts more burden on display devices, we also create a helper function for panels to add a single DRM mode from the panel video timings.
