Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

- * This driver is for the 'Mark Of The Unicorn' (MOTU)
- * MidiTimePiece AV multiport MIDI interface
- *
- * IOPORTS
- * -------
- * 8 MIDI Ins and 8 MIDI outs
- * Video Sync In (BNC), Word Sync Out (BNC),
- * ADAT Sync Out (DB9)
- * SMPTE in/out (1/4")
- * 2 programmable pedal/footswitch inputs and 4 programmable MIDI controller knobs.
- * Macintosh RS422 serial port
- * RS422 "network" port for ganging multiple MTP's
- * PC Parallel Port ( which this driver currently uses )
- *
- * MISC FEATURES
- * -------------
- * Hardware MIDI routing, merging, and filtering
- * MIDI Synchronization to Video, ADAT, SMPTE and other Clock sources
- * 128 'scene' memories, recallable from MIDI program change
- *
- *
- * ChangeLog
- * Jun 11 2001 Takashi Iwai <tiwai@suse.de>
- * - Recoded & debugged
- * - Added timer interrupt for midi outputs
- * - hwports is between 1 and 8, which specifies the number of hardware ports.
- * The three global ports, computer, adat and broadcast ports, are created
- * always after h/w and remote ports.
- *
