drm: rcar_lvds: Fix dual link mode operations
The R-Car LVDS encoder units support dual-link operations by splitting
the pixel output between the primary encoder and the companion encoder.
Currently the companion encoder fails at probe time, causing the
registration of the primary to fail as well, preventing the whole DU unit
from being registered at all.
Fix this by not bailing out from probe with error if the
"renesas,companion" property is not specified.
