Some platforms may have support for offloading USB audio devices to a dedicated audio DSP. Introduce a set of APIs that allow for management of USB sound card and PCM devices enumerated by the USB SND class driver. This allows for the ASoC components to be aware of what USB devices are available for offloading.

Do we really want to build this into ASoC core unconditionally? This is very specific to Qualcomm USB-offload stuff, so it's better to factor out.
