drm/omap: Don't call .set_timings() operation recursively

Browse Source 
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.
