ALSA: usb-audio: rework add_control_to_empty()
This patch renames add_control_to_empty() to snd_usb_mixer_add_control() and exports it, so the quirks functions can make use of it. Also, as "struct mixer_build" is private to mixer.c, rewrite the function to take an argument of type "struct usb_mixer_interface" instead.
