Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * Changes:
- *
- * Dec. 19, 2002	Takashi Iwai <tiwai@suse.de>
- *	- use the DSX channels for the first pcm playback.
- *	  (on VIA8233, 8233C and 8235 only)
- *	  this will allow you play simultaneously up to 4 streams.
- *	  multi-channel playback is assigned to the second device
- *	  on these chips.
- *	- support the secondary capture (on VIA8233/C,8235)
- *	- SPDIF support
- *	  the DSX3 channel can be used for SPDIF output.
- *	  on VIA8233A, this channel is assigned to the second pcm
- *	  playback.
- *	  the card config of alsa-lib will assign the correct
- *	  device for applications.
- *	- clean up the code, separate low-level initialization
- *	  routines for each chipset.
- *
- * Sep. 26, 2005	Karsten Wiese <annabellesgarden@yahoo.de>
- *	- Optimize position calculation for the 823x chips.
