sound: usb: Add support for parsing AudioStreaming intf for BADD devices
BADD(Basic Audio Device Definition) is a subset of UAC3
specifications. It defines standard profiles which provide
specific attributes of class descriptors. BADD audio device
provides profile id and BADD supporting host will infer
attributes from profile-id.
Currently USB Audio Host driver has support for UAC1
and UAC2 devices. To handle BADD 3.0 devices, AudioControl
and AudioStreaming Interfaces have to be properly parsed.
The Host has to derive all class-specific information based
on the profile ID that the device exposes. Add support for
parsing the AudioStreaming interfaces exposed by the device.
