 Steps

  * Boot holding volume down btn - ensure the audio is muted under OFW
  * Reboot - Linux hangs right after "usbhid: USB HID core driver". In a
 normal boot, the message that follows usually is  "asoc: alc5631-hifi <->
 mmp2-i2s.0 mapping ok"

 It seems likely that OFW does not init audio if the volume is muted, and
 that the Linux driver is counting on OFW pre-initializing it.
