Fixes for veyron chromebooks

[GitHub pull_request - opened]

alsa-project/alsa-ucm-conf pull request #164 was opened from jenneron:

Add PlaybackVolume and JackControl. I didn't add JackControl for headset mic because internal mic breaks after switching to headset and back

Add symlink to VEYRON-I2S, so ucm config will get probed
