Subject: [PATCH 2/2] arm64: dts: qcom: x1e80100-romulus: Set up USB
 Multiport controller

From: Konrad Dybcio <quic_kdybcio@...cinc.com>

The USB MP controller is wired up to the USB-A port on the left side
and to the Surface Connector on the right side. Configure it.

While at it, remove a stray double \n.
