[PATCH v2 4/5] arm64: dts: qcom: sm6350: Add q6usbdai node

[Luca Weiss]

Add a node for q6usb which handles USB audio offloading, allowing to
play audio via a USB-C headset with lower power consumption and enabling
some other features.

We also need to set num-hc-interrupters for the dwc3 for the q6usb to be
able to use its sideband interrupter.
