Currently disconnect callback is used as a driver's destructor, and
this has to be called not only at the disconnection time but also at
the error paths during probe.

It's utterly unsafe to proceed further the disconnect procedure if the
assigned usbdev is inconsistent with the expected object. Better to
put a WARN_ON() for more cautions and abort immediately.

The driver version string was removed in an ealier commit for being
useless. These are equally useless.

The correct spelling includes the space. Fix this in strings and
comments that refer to the manufacturer.

Call line6_pcm_disconnect() at disconnect to make sure that all URBs
are cleared. Also reduce the superfluous snd_pcm_stop() calls from
the function (and remove the unused function) since the streams are
guaranteed to be stopped at this point via snd_card_disconnect().

Calling line6_pcm_disconnect() at suspend callback is superfluous and
rather confusing. Let's get rid of it.

This is rather useless for a driver that has been already merged into
the official tree.

This is a fairly big rewrite regarding the card resource management in
line6 drivers:
- The card creation is moved into line6_probe(). This adds the global
destructor to private_free, so that each driver doesn't have to call
it any longer.
- The USB disconnect callback handles the card release, thus each
driver needs to concentrate on only its own resources. No need to
snd_card_*() call in the destructor.
- Fix the potential stall in disconnection by removing
snd_card_free(). It's replaced with snd_card_free_when_closed()
for asynchronous release.
- The only remaining operation for the card in each driver is the call
of snd_card_register(). All the rest are dealt in the common module
by itself.
- These ended up with removal of audio.[ch] as a result of a reduction
of one layer. Each driver just needs to call line6_probe().

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.

Promote line6 driver from staging to sound/usb/line6 directory, and
maintain through sound subsystem tree.
This commit just moves the code and adapts Makefile / Kconfig.
The further renames and misc cleanups will follow.
