drm/sun4i: move rgb mode_valid from connector to encoder 

mode_valid function must be connected to encoder.
Otherwise it could get not be called by drm in the case there's a
bridge connected to encoder instead of a panel.

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