drm/sysfs: split DVI-I and TV-out attributes
The show methods for the attributes of DVI-I and TV-out types have a bunch of code to deal with the differences between the two. Just split the attributes into connector type specific ones. No functional changes. Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
