Subject: [PATCH v2] arm64: dts: rockchip: fix px30 lvds ports

From: Heiko Stuebner <heiko.stuebner@...obroma-systems.com>

The lvds controller has two ports. port@0 for the connection
to the display controller(s) and port@1 for the connection to
the panel, so should have a ports node covering the port@x nodes.

- removed global #address+size-cells from lvds as suggested by Robin Murphy
