Add support for AVIRT
Leverage the new AVIRT driver for a more secure, more dynamically configurable loopback sound driver. To use, replace the file smixer-4a-default.json with smixer-4a-avirt.json, at /usr/libexec/agl/smixer/etc. The snd-avirt drivers are installed in AGL by default as of 6.99.2. The existing snd-aloop configuration is not broken by this change. Change-Id: I827636656c109a7393ad77997e05069a2462ea46 Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>
