* EVS camera HAL supports UVC USB webcams. CSI camera modules are not
supported with EVS. CSI camera modules need to be disconnected when using
EVS so that UVC USB webcam will populate the first video device
(/dev/video0).
* Enable default Android camera service so regular camera apps can be used
as well (CSI camera modules & UVC USB webcams).
* Fixes https://github.com/raspberry-vanilla/android_local_manifest/issues/23
* Audio
- Based on AOSP hikey audio HAL:
https://android.googlesource.com/device/linaro/hikey/+/refs/heads/master/audio/
- ALSA based on Android-x86
- ALSA loop is used to support HDMI audio on Pi 4 because VC4 HDMI
audio devices use SNDRV_PCM_FORMAT_IEC958_SUBFRAME_LE that is not
supported on Android
