The VENC driver currently relies on the omap_dss_device struct to configure the venc type. This makes the VENC interface driver dependent on the omap_dss_device struct. Make the VENC driver data maintain it's own 'venc type' field. A panel driver is expected to call omapdss_venc_set_type() before enabling the interface or changing the type via display sysfs attributes.
