ALSA: line6: Add support for POD X3
This includes audio in/out and basic initialization via control EP (emulates what original driver does). The initialization is done similarly to original POD, firmware and serial IDs are read and exported via sysfs. Signed-off-by: Andrej Krutak <dev@andree.sk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
