arm64: dts: rockchip: Fix LCD panel port on rk3566-pinetab2

The MIPI DSI connector on the PineTab2 only has 1 port with 1 endpoint,
so drop the unit-address properties.

While at it, move 'rotation' property to its proper sorting position.

This fixes the following DTB validation warnings:

  node has a unit name, but no reg or ranges property
