ALSA: move line6 usb driver into sound/usb

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.

-	help
-	  This is a driver for the guitar amp, cab, and effects modeller
-	  PODxt Pro by Line6 (and similar devices), supporting the
-	  following features:
-	    * Reading/writing individual parameters
-	    * Reading/writing complete channel, effects setup, and amp
-	      setup data
-	    * Channel switching
-	    * Virtual MIDI interface
-	    * Tuner access
-	    * Playback/capture/mixer device for any ALSA-compatible PCM
-	      audio application
-	    * Signal routing (record clean/processed guitar signal,
-	      re-amping)
-
-	  Preliminary support for the Variax Workbench and TonePort
-	  devices is included.

-	help
-	  Say Y here to add code to measure the impulse response of a Line6
-	  device. This is more accurate than user-space methods since it
-	  bypasses any PCM data buffering (e.g., by ALSA or jack). This is
-	  useful for assessing the performance of new devices, but is not
-	  required for normal operation.
-

-	There are several features of the Line6 USB driver which require PCM
-	data to be exchanged with the device:
-	*) PCM playback and capture via ALSA
-	*) software monitoring (for devices without hardware monitoring)
-	*) optional impulse response measurement
-	However, from the device's point of view, there is just a single
-	capture and playback stream, which must be shared between these
-	subsystems. It is therefore necessary to maintain the state of the
-	subsystems with respect to PCM usage. We define several constants of
-	the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
-	following meanings:
-	*) <subsystem> is one of
-	-) ALSA: PCM playback and capture via ALSA
-	-) MONITOR: software monitoring
-	-) IMPULSE: optional impulse response measurement
-	*) <direction> is one of
-	-) PLAYBACK: audio output (from host to device)
-	-) CAPTURE: audio input (from device to host)
-	*) <resource> is one of
-	-) BUFFER: buffer required by PCM data stream
-	-) STREAM: actual PCM data stream
-
-	The subsystems call line6_pcm_acquire() to acquire the (shared)
-	resources needed for a particular operation (e.g., allocate the buffer
-	for ALSA playback or start the capture stream for software monitoring).
-	When a resource is no longer needed, it is released by calling
-	line6_pcm_release(). Buffer allocation and stream startup are handled
-	separately to allow the ALSA kernel driver to perform them at
-	appropriate places (since the callback which starts a PCM stream is not
-	allowed to sleep).
