[PATCH 2/2] drm/bridge: tc358768: switch to bus-width

[Krzysztof Kozlowski]

"data-lines" property is way too similar to "data-lanes".  It is also
duplicating "bus-width" from video-interfaces.yaml schema.  "data-lines"
was deprecated in the bindings and "bus-width" is preferred, so parse it
instead while keeping things backwards compatible.
