drm: rcar-du: Skip LVDS1 output on Gen3 when using dual-link LVDS mode

Browse source

In dual-link LVDS mode, the LVDS1 encoder is used as a companion for
LVDS0, and both encoders transmit data from DU0. The LVDS1 output of DU1
can't be used in that case, don't create an encoder and connector for
it.
