ALSA jack detection support
Adds support for ALSA jack detection for USB.
Spawns a new thread for ALSA jack detection on device
insert. If the device doesn't support ALSA jack detection,
the thread terminates.
Test: UAC2 audio accessory and a kernel
which supports USB ALSA Jack detection, switching between
speaker and USB works perfectly with plug/unplug at jack.
