drm/omap: displays: Remove input omap_dss_device from panel data

Browse Source 
All connectors, encoders and panels store a pointer to their input
omap_dss_device in the panel driver data structure. This duplicates the
src field in the omap_dss_device structure. Remove the private copy and
use the src field.
