[PATCH 1/2] dt-bindings: display: bridge: icn6211: Document DSI data-lanes property

[Marek Vasut]

It is necessary to specify the number of connected/used DSI data lanes when
using the DSI input port of this bridge. Document the 'data-lanes' property
of the DSI input port.

NOTE: This is consistent with all the other DSI panel and bridge bindings which
      document 'data-lanes' property, all of which already use OF graph and have
      the 'data-lanes' property in the port at N subnode, see:
      $ git grep -l data-lanes Documentation/devicetree/bindings/display/
