audio: Create AC97 device with --ac97 option
1. Replace --cras-audio, --cras-capture, null-audio options by --ac97 option to create audio devices. 2. "--ac97 backend=BACKEND\ [capture=true,capture_effect=EFFECT]" is comma separated key=value pairs for setting up Ac97 devices. It can be given more than once to create multiple devices. Possible key values are: backend=(null, cras) - Where to route the audio device. `null` for /dev/null, and cras for CRAS server. capture=true - Enable audio capture. capture_effects - | separated effects to be enabled for recording. The only supported effect value now is EchoCancellation or aec. BUG=b:140866281 TEST=1.crosvm run -r ./vm_rootfs.img -c 4 -m 1024 -s /run --cid 5 --host_ip\ 100.115.92.25 --netmask 255.255.255.252 --ac97\ backend=cras,capture=true,capture_effect=aec\ --mac d2:47:f7:c5:9e:53 ./vm_kernel 2. Record with the vm by: arecord -D hw:0,0 -d5 -fS16_LE -c2 -r48000 /tmp/test.mp3 3. Verify that AEC is enabled within the recording stream by cras_test_cleint.
