Moved, renamed, and deleted files

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

- *  Copyright (c) 2004 James Courtier-Dutton <James@superbug.demon.co.uk>
- *  Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
- *  Version: 0.0.25
- *
- *  FEATURES currently supported:
- *    Front, Rear and Center/LFE.
- *    Surround40 and Surround51.
- *    Capture from MIC an LINE IN input.
- *    SPDIF digital playback of PCM stereo and AC3/DTS works.
- *    (One can use a standard mono mini-jack to one RCA plugs cable.
- *     or one can use a standard stereo mini-jack to two RCA plugs cable.
- *     Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
- *    ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
- *    Notes on how to capture sound:
- *      The AC97 is used in the PLAYBACK direction.
- *      The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
- *      So, to record from the MIC, set the MIC Playback volume to max,
- *      unmute the MIC and turn up the MASTER Playback volume.
- *      So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
- *   
- *    The only playback controls that currently do anything are: -
- *    Analog Front
- *    Analog Rear
- *    Analog Center/LFE
- *    SPDIF Front
- *    SPDIF Rear
- *    SPDIF Center/LFE
- *   
- *    For capture from Mic in or Line in.
- *    Digital/Analog ( switch must be in Analog mode for CAPTURE. )
- * 
- *    CAPTURE feedback into PLAYBACK
- * 
- *  Changelog:
- *    Support interrupts per period.
- *    Removed noise from Center/LFE channel when in Analog mode.
- *    Rename and remove mixer controls.
- *  0.0.6
- *    Use separate card based DMA buffer for periods table list.
- *  0.0.7
- *    Change remove and rename ctrls into lists.
- *  0.0.8
- *    Try to fix capture sources.
- *  0.0.9
- *    Fix AC3 output.
- *    Enable S32_LE format support.
- *  0.0.10
- *    Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
- *  0.0.11
- *    Add Model name recognition.
- *  0.0.12
- *    Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
- *    Remove redundent "voice" handling.
- *  0.0.13
- *    Single trigger call for multi channels.
- *  0.0.14
- *    Set limits based on what the sound card hardware can do.
- *    playback periods_min=2, periods_max=8
- *    capture hw constraints require period_size = n * 64 bytes.
- *    playback hw constraints require period_size = n * 64 bytes.
- *  0.0.15
- *    Minor updates.
- *  0.0.16
- *    Implement 192000 sample rate.
- *  0.0.17
- *    Add support for SB0410 and SB0413.
- *  0.0.18
- *    Modified Copyright message.
- *  0.0.19
- *    Finally fix support for SB Live 24 bit. SB0410 and SB0413.
- *    The output codec needs resetting, otherwise all output is muted.
- *  0.0.20
- *    Merge "pci_disable_device(pci);" fixes.
- *  0.0.21
- *    Add 4 capture channels. (SPDIF only comes in on channel 0. )
- *    Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.)
- *  0.0.22
- *    Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901
- *  0.0.23
- *    Implement support for Line-in capture on SB Live 24bit.
- *  0.0.24
- *    Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
- *  0.0.25
- *    Powerdown SPI DAC channels when not in use
- *
- *  BUGS:
- *    Some stability problems when unloading the snd-ca0106 kernel module.
- *    --
- *
- *  TODO:
- *    4 Capture channels, only one implemented so far.
- *    Other capture rates apart from 48khz not implemented.
- *    MIDI
