OMAPDSS: VENC: allow switching venc output type at runtime
VENC output type (composite/svideo) doesn't have to be fixed by board wiring, it is possible to also provide composite signal through svideo luminance connector (software enabled), which is what pandora does. Having to recompile the kernel for users who have TV connector types that don't match default board setting is very inconvenient, especially for users of a consumer device, so add support for switching VENC output type at runtime over a new sysfs file output_type.
