arm64: dts: qcom: sm7225-fairphone-fp4: Enable USB audio offload support
Enable USB audio offloading which allows to play audio via a USB-C
headset with lower power consumption and enabling some other features.
This can be used like the following:
$ amixer -c0 cset name='USB_RX Audio Mixer MultiMedia1' On
$ aplay --device=plughw:0,0 test.wav
Compared to regular playback to the USB sound card no xhci-hcd
interrupts appear during playback, instead the ADSP will be handling the
USB transfers.
