dt-bindings: display: nwl-dsi: Allow 'data-lanes' property for port@1 



This controller support scalable data lanes from 1 to 4. Add the
'data-lanes' property to configure the number of MIPI display panel lanes
selected for boards.

Change $ref of port@1 from 'port' to 'port-base' and add 'endpoint'
property referencing video-interfaces.yaml. Allow 'data-lanes' values
1, 2, 3, and 4 for port@1.

Fix below CHECK_DTB warnings:
arch/arm64/boot/dts/freescale/imx8mq-tqma8mq-mba8mx-lvds-tm070jvhg33.dtb:
 dsi@30a00000: ports:port@1:endpoint: Unevaluated properties are not allowed ('data-lanes' was unexpected)
