drm/sun4i: tcon: Set output mux for DSI and LVDS

Browse Source 
DSI and LVDS skip output mux setup, so TCON TOP cannot route the selected
mixer. Configure them like other channel 0 outputs.

In practice this matters for D1, where channel 0 TCONs are fed through
TCON TOP. The remaining set_mux implementations only handle TMDS and
return an error for other encoder types, as before.
