This makes the VENC interface driver dependent on the omap_dss_device struct. Make the VENC driver data maintain it's own timings field. The panel driver is expected to call omapdss_venc_set_timings() to set these timings before the panel is enabled. Make the VENC panel driver configure the new timings is the omap_dss_device struct(dssdev->panel.timings). The VENC driver is responsible for maintaining only it's own copy of timings.
