[PATCH 03/12] arm64: dts: qcom: qcs6490-radxa-dragon-q6a: Enable USB 3.0 and HDMI ports

[Xilin Wu]

This board doesn't feature a regular Type-C port. The usb_1_qmpphy's
RX1/TX1 pair is statically connected to the USB-A port, while its RX0/TX0
pair is connected to the RA620 DP-to-HDMI bridge.

Add and enable the nodes for the features to work.
