ALSA: usb-audio: make set_*_mix_values functions public
Make the functions set_cur_mix_value and get_cur_mix_value accessible by files
that include mixer.h. In addition make usb_mixer_elem_free accessible.
This allows reuse of these functions by mixers that may require quirks.
The following summarizes the renamed functions:
- set_cur_mix_value -> snd_usb_set_cur_mix_value
- get_cur_mix_value -> snd_usb_get_cur_mix_value
- usb_mixer_elem_free -> snd_usb_mixer_elem_free
