sound: usb: Populate tunnel mode response struct for BADD devices

For tunnel mode audio functionality, we need to populate
some fields of the QMI response structure with some UAC
device exposed values namely bDelay, bcdADC and
SubSlotSize. Add support for filling in subslotsize
field for BADD 3.0 devices. bDelay and bcdADC fields
are not supported in Audio 3.0 devices.
