Subject: [PATCH 1/2] arm64: dts: rockchip: Simplify usb-c-connector port on
 rk3566-pinenote

The USB-C connector on the PineNote has only 1 port, so there's no need
for a 'ports' node with address-/size-cells properties as a single
'port' node suffices.

This fixes the following DT validation issue:

  Warning (graph_child_address): /i2c@...c0000/tcpc@...connector/ports:
    graph node has single child node 'port@0',
    #address-cells/#size-cells are not necessary
