Subject: [PATCH 1/2] arm64: dts: qcom: sm8550: Fix compile warnings in USB controller node

With W=1, the following error comes up:

Warning (avoid_unnecessary_addr_size): /soc@...sb@...0000: unnecessary #address-cells/#size-cells without "ranges", "dma-ranges" or child "reg" or "ranges" property

This is because the child node being removed during flattening and moving
to latest bindings.

Fixes: 33450878adfc ("arm64: dts: qcom: sm8550: Flatten the USB nodes")
