[PATCH] arm64: dts: qcom: hamoa-iot-evk: Enable retimer on USB0 port

[Prashanth K <prashanth.k@oss.qualcomm.com>]

Currently while connecting super-speed devices to the usb_1_ss0
(USB0 port), it falls back to high-speed. Add the retimer for
USB0 port, enabling super-speed enumeration on that port.
