This patch fixes this problem and also adds an error check in a place

Comment in hda_intel.c states that 'the explicit resume is needed only
when POWER_SAVE isn't set', but this is not true.
There is no code that will automaticly power up the codec on resume,
but only code that powers it up when user accesses it. So if user
leaves a sound playing, codec will not be powered
To fix that I check if there are any codecs that should be powered
codec->power_count, and if so I power them up together with main
controller.

hda_power_work will not shut down the codec, but nether will clear

Added CONFIG_SND_HDA_POWER_SAVE kconfig.  It's an experimental option
to achieve an aggressive power-saving.  With this option, the driver
will turn on/off the power of each codec and controller chip dynamically
on demand.
The patch introduces a new module option 'power_save'.  It specifies
the second of time-out for automatic power-down.  As default, it's
10 seconds.  Setting 0 means to suppress the power-saving feature.
The codec may have analog-input loopbacks, which are usually represented
by mixer elements such as 'Mic Playback Switch' or 'CD Playback Switch'.
When these are on, we cannot turn off the mixer and the codec chip has
to be kept on.  For bookkeeping these states, a new codec-callback is
introduced.
For the bus-controller side, a new callback pm_notify is introduced,
which can be used to turn on/off the contoller appropriately.
Note that this power-saving might cause slight click-noise at
power-on/off.  Also, it might take some time to wake up the codec, and
might even drop some tones at the very beginning.  This seems to be the
side-effect of turning off the controller chip.
This turn-off of the controller can be disabled by undefining
HDA_POWER_SAVE_RESET_CONTOLLER in hda_intel.c.

So far, the driver looked the table of snd_kcontrol_new used for creating
mixer elements and forces to call each of its put callbacks in PM resume
code.  This is too ugly and hackish.
Now, the resume is simplified using the codec amp and command register
caches.  The driver simply restores the values that have been written
in the cache table.  With this simplification, most codec support codes
don't require any special resume callback.

This patch adds the cache for codec command registers.

The patch introduces only the framework, and no codec code is using
this cache yet.  It'll be implemented in the following patch.

STAC922x provides the capture boost level up to 4, but actually it
works only up to 2.  Since the range of the mixer is automatically

purpose.
