Added probe_only module option to hd-audio driver.
This option specifies whether the driver creates and initializes the
codec-parser after probing. When this option is set, the driver skips
the codec parsing and initialization but gives you proc and other
accesses. It's useful to see the initial codec state for debugging.
The default of this value is off, so the default behavior is as same
as before.

The global functions in hda_codec.c and other core parts are only
for HD-audio codec and controller drivers. When the HD-audio driver
is built in kernel, all stuff have to be statically linked, thus
we don't need any exports.
This patch introduces a conditional macro to do export only
when needed.

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

The reconfiguration of PCM affected all PCM streams on the bus, but
this this should be done rather only for the target codec.
This patch does the following:
- introduce bitmap indicating the PCM device usages on a hda_bus
- refactor the PCM build functions
- fix __devinit prefix in some fucntions
- add a proper ifdef around HDA-reconfig-specific functions

SPDIF status bits controls are written via snd_hda_codec_write()
without caching. This causes a regression at resume that the bits
are lost.
Simply replacing it with the cached version fixes the problem.

The jack instances created in patch_sigmatel.c may be double-freed.
The device management code checks the invalid element, and thus there
is no real breakage, but it spews annoying warning messages.
But, we can't simply remove the release calls of these jack instances
because they have to be freed when the codec is re-configured.
Now, a new flag, bus->shutdown is introduced to indicate that the bus
is really being unloaded, i.e. the objects managed by the device
manager will be automatically deleted. We release these objects only
when this flag isn't set.

The SPDIF output is toggled at each time any SPDIF status bits are changed
because of the known problems on some codecs. But, this also results in
loosing the sync, and the problem is more obvious on HDMI output over
SPDIF. Since the toggle is necessary only for some codecs, we should
check whether this workaround is needed and skip if unnecessary.
