staging: line6: add Pod HD300 support
The Pod HD device family uses new MIDI SysEx messages and therefore cannot reuse the existing Pod code. Instead of hardcoding Pod HD MIDI messages into the driver, leave MIDI up to userspace. This driver simply presents MIDI and pcm ALSA devices. This device is similar to the Pod except that it has 48 kHz audio and does not respond to Pod SysEx messages.
