Split to each individual driver for POD, PODHD, TonePort and Variax with a core LINE6 helper module. The new modules follow the standard ALSA naming rule with snd prefix: snd-usb-pod, snd-usb-podhd, snd-usb-toneport and snd-usb-variax, together with the corresponding CONFIG_SND_USB_* Kconfig items.
