hda_component.h uses hda_codec_dev from sound/hda_codec.h.
Include sound/hda_codec.h instead of assuming that it has already
been included by the parent .c file.
This isn't causing any problems with current code, so no need to
backport to older kernels.

Add the conventional include guards around the content of the
hda_component.h header file. This prevents double-declaration of
struct hda_component if the header gets included multiple times.
This isn't causing any problems with current code, so no need to
backport to older kernels.

Move the generic parts of the hda_component implementation into a new
hda_component module. This will allow other HDA codecs to add support
for the component binding API without duplicating all the code.

Some systems support a notification from ACPI, which can be used
for different things.
Only one handler can be registered for the acpi notification, but all
amps need to receive that notification, we can register a single handler
inside the component master, so that it can then notify through the
component framework.
This is required to support mute notifications from ACPI.

These hooks can be used to add callbacks that would be run before and after
the main playback hooks. These hooks would be called for all amps, before
moving on to the next hook, i.e. pre_playback_hook would be called for
all amps, before the playback_hook is called for all amps, then finally
the post_playback_hook is called for all amps.

The current code uses calls from the HDA Codec driver to
determine when to suspend/resume by calling hooks via the
hda_component binding.
However, this means the cs35l41 driver relies on the HDA
Codec driver to tell it when to suspend or resume,
creating an additional external dependency, and potentially
creating race conditions in the future. It is better for
the cs35l41 hda driver to decide for itself when the part
should be suspended or resumed.
This makes supporting system suspend easier.

CS35L41 supports hibernation during suspend when using
DSP firmware.
When the driver suspends it will hibernate the part, if
firmware is running, and resume will wake from hibernation.
CS35L41 driver will suspend/resume when requested by
hda driver.
Note that suspend/resume and hibernation is only supported
when firmware is running.

This API was required for CLSA0100 laptop, which did not
have correct properties inside ACPI. The required values
are now hardcoded inside the driver so this is no longer
needed.
Without this api, there CLSA0100 can now use the generic
cs35l41 fixup, like the other laptops.
All other laptops will read the Speaker Position from
ACPI and set the channel map from within the driver.
