The power-state changes in patch_sigmatel.c are accessed via *_cached()
but they shouldn't be really cached.  Fixed to the normal write.

Also, stac92hd71xx_suspend and resume are no longer necessary as the
power-state changes are handled properly in the common routine.
Removed these hacks now.

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

Since we need to handle many unsolicited events assigned to different
widgets, allocate the event dynamically using the existing events
array, and use the tag appropriately instead of combination of fixed
number and widget nid.  (Note that widget nid can be over 4 bits!)

Also, replaced the call of unsol_event handler with a dedicated
function to be more readable.

The AFG pin power-mapping isn't properly set for the fixed I/O pins
on IDT 92HD* codecs.  This resulted in the low power mode after the
boot until any jack detection is executed, thus no output from the
speaker.

This patch fixes the power mapping for the fixed pins, and also fixes
the GPIO bits and digital I/O pin settings properly in stac92xx_ini().

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.

Due to the recent change for multiple HP as line-out switch, only
one of the multiple headphons (usually a wrong one) is toggled
and the other pins are still disabled.  This causes the silent output
problem on some Dell laptops.

Also, the hp_switch check is screwed up when a line-in or a mic-in
jack exists.  This is added as an additional output, but hp_switch
check doesn't take it into account.

This patch fixes these issues: simplify hp_switch check by using
the NID instead of bool, and clean up / fix the toggle of HP pins
in unsol event handler code.

The input pins are sometimes not initialized properly because
of the optimization check of the current pinctl code.

Force to initialize the mic input pins so that they can be set up
properly even if they were in a weird state.  But keep other input
pins if already set up as input, since this could be an extra mic
pin.

This patch adds support to the IDT codec families to report jack status
to the jack abstraction layer. This required some reorganization in the
stac92xx_unsol_event function in which the index value is changed to
reporting the nid with the event.

Also adds an sigmatel_jack struct to keep track of the nid relation
to the jack abstraction layer instance. Also adds functions to set and
retrieve data values for each nid, this is used in stac92xx_unsol_event
to retrieve the GPIO mask for STAC_VREF_EVENT.
