sound: usb: Add support for parsing AudioControl intf for BADD devices
BADD 3.0 devices support three types of topologies;
Basic I/P, Basic O/P, and BASIC I/P. Accordingly, various
units and terminals have to be parsed which are not
exposed by the device and host must be able to figure
out various class-specific descriptors based on the
profile ID of the device. This patch adds this logic
to build various units and terminals of the AudioControl
interface of a BADD device.
