The VENC driver currently relies on the timings in omap_dss_device struct to
configure the DISPC and VENC blocks accordingly. 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.
