drm/omap: Don't call .set_timings() operation recursively
Instead of calling the .set_timings() operation recursively from the display device backwards, iterate over the devices manually in the DRM encoder code. This moves the complexity to a single central location and simplifies the logic in omap_dss_device drivers.
