port-arm/49057: Raspberry Pi Audio volume control does not work
- Use software volume control for outputs.master/inputs.dac
- Previous volume control (for analog output only) is available on new
  outputs.headphones mixer control.
- Add an outputs.select enum to choose between "auto", "headphones", and
  "hdmi" outputs.

port-arm/49057: Raspberry Pi Audio volume control does not work
AUDS server messages expect volume to be expressed in units of 1/256 dB,
where we previously (incorrectly) treated it as as percentage. Map the
NetBSD audio level (0-255) to 20 steps (levels from FreeBSD bcm2835_audio.c)
and provide independent volume knobs for outputs.auto, outputs.hdmi, and
outputs.headphones.
