adbd: Add USB Super Speed (3.0) support

When using FunctionFS, adbd is required to specify USB
descriptors as well for ADB function. If underlying host
and device support USB3.0 then USB communication works
if all interface drivers provide SS descriptors as well.
Since, ADBD currently doesn't pass SS descriptors to the
function_fs driver, it results in USB enumeration failure
in SuperSpeed mode when ADB is enabled in USB composition.
