ALSA: usb-audio: Allow for rediscovery of connected USB SND devices
In case of notifying SND platform drivers of connection events, some of
these use cases, such as offloading, require an ASoC USB backend device to
be initialized before the events can be handled. If the USB backend device
has not yet been probed, this leads to missing initial USB audio device
connection events.
Expose an API that traverses the usb_chip array for connected devices, and
to call the respective connection callback registered to the SND platform
driver.
