Add initial recipes for snd-avirt driver
The snd-avirt driver will provide an enhanced, dynamic ALSA loopback
interface for 4a-softmixer, and provides the audio framework for
low-latency audio hardmixers such as the Fiberdyne DSP onboard the
Xtensa HiFi2, and the UNICENs Fiberdyne smart amplifier.
Included are backport patches for kernels 4.12 and 4.9.
