Subject: [PATCH v4 09/10] arm64: dts: rockchip: Drop unneeded address+size-cells on px30

On nodes with compatible "rockchip,px30-usb2phy-grf", the #address-cells
and #size-cells are required and consequently their child nodes should
have unit addresses. That is not the case for the px30-pmugrf and
px30-grf nodes, so remove them there.

This fixes the following DTB validation warnings:

  unnecessary #address-cells/#size-cells without "ranges",
  "dma-ranges" or child "reg" property
