snd_bcm2835: disable HDMI audio when vc4 is used (#3640)
Things don't work too well when both the vc4 driver and the firmware
driver are trying to control the same audio output:
[ 763.569406] bcm2835_audio bcm2835_audio: vchi message timeout, msg=5
Hence, when the vc4 HDMI driver is used, let it control audio. This is done
by introducing a new device tree property to the audio node, and
extending the vc4-kms-v3d overlays to set it appropriately.
