	linux/usb/audio.h: split header
- Split the audio.h file in two to clearly denote the differences between the standards. - Add many more defines to audio-v2.h. Most of them are not currently used. - Replaced a magic value with a proper define Signed-off-by: Daniel Mack <daniel@caiaq.de> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Cc: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
