Split the monolithc HD-audio driver into several pieces:
- snd-hda-intel HD-audio PCI controller driver; loaded via udev
- snd-hda-codec HD-audio codec bus driver
- snd-hda-codec-* Specific HD-audio codec drivers
When built as modules, snd-hda-codec (that is invoked by snd-hda-intel)
looks up the codec vendor ID and loads the corresponding codec module
automatically via request_module().
When built in a kernel, each codec drivers are statically hooked up
before probing the PCI.
This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module
information for each driver, and driver-linking codes between
codec-bus and codec drivers.
TODO:
- Avoid EXPORT_SYMBOL*() when built-in kernel
- Restore __devinit appropriately depending on the condition

ELD handling routines can be shared by all HDMI codecs,
and they are large enough to make a standalone source file.

Use a private array for TLV entries of virtual master controls instead
of (supposed) static array. This cleans up the existing codes.
Also, now vmaster assumes the simple dB-range TLV that is the only type
it can handle.

Added helper functions to implement virtual master volume controls.
The virtual master control is a control element that has multiple
slave controls. The value of master element is equally added to
slave elements.
The functions are written for general purpose, but it's put in the
HD-audio directory as now, since HD-audio driver is the only user.
It should be moved to the common place once after other drivers use
vmaster.

Merge hda-codec module to a single hda-intel module since this is the
only user right now. Although hda-codec stuff is designed to be used
universally from different controller drivers, currently only one
controller interface (and compatibles) are used. So, let's merge them
to a single module to save memory.

This driver adds limited support for the Conexant 5045 and 5047 HD Audio
codecs. Some issues still need to be resolved. The code is based
primarily on code from the Analog Devices AD1981 support and the Realtek
ALC260 support. Some code came from the original code developed by Alex
Pototskiy (see alsa bugtracker 2485).

HDA generic driver,HDA Codec driver
Add initial SigmaTel codec support for 9200 and 922x. Note that
this hda patch relies on the configuration default registers to
be set correctly (normally by BIOS/firmware) in order for it to
set up pin widgets properly. There's a test switch in the patch
so it will work with the SigmaTel reference boards that are usually
plugged into a system that doesn't set the configuration default
registers. It supports 2 channel analog out and line/mic in. I
plan to add >2 channel support and spdif support shortly.
Please apply.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
