arm64: dts: qcom: ipq9574: Complete USB DWC3 wrapper interrupts

Complete interrupts for DWC3 node to match what is required by
Devicetree bindings, as reported by dtbs_check:

  ipq9574-rdp433.dtb: usb@8af8800 (qcom,ipq9574-dwc3): interrupt-names: ['pwr_event'] is too short

The actual interrupt numbers are taken from reference manual of similar
chip, but not IPQ9574, due to lack of access to it.
