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.
