Subject[PATCH] drm/sun4i: move rgb mode_valid from connector to encoder
Date
mode_valid function must be connected to encoder, not connector.
Otherwise it doesn't get called by drm.

Move mode_valid function pointer to encoder helper functions,
changing its prototype according to encoder helper function pointer.
