The use of venc_panel.c was removed in
09d2e7cdebd53b7572380a215008b334ff6321a5 (OMAPDSS: VENC: remove code
related to old panel model), but the file itself was left behind. Remove
the unused file.

Add support to handle HPD GPIO in the HDMI connector driver. For the
time being, the driver only uses HPD GPIO to report is the cable is
connected via detect() calll.
