Override vendor's usb_audio_policy_configuration
Android 8.1 added the support for new type of USB Audio devices
(USB_HEADSET, instead of old USB_DEVICE)
Some older USB devices got converted to this USB_HEADSET while still
using the old protocol.
There is no driver change needed, but the audio policy needs to be
changed.
Since vendors are simply using AOSP usb_audio_policy_configuration
Override it by ourself.
