ALSA: scarlett2: Add power status control

Browse source

Add a control to retrieve the power status from the interface
(bus-powered, external-powered, or insufficient power).

Mark the new scarlett2_notify_power_status() function with
__always_unused until it gets used when the Gen 4 notification
callback function arrays are added.
