Convert the C-Media codec driver to use the new hda_codec_ops probe.
Since the CM9825 uses a completely different probe and codec ops,
factor out to an individual codec driver, snd-hda-codec-cm9825.
Other than that, no functional changes.

In the past, we unified HD-audio HDMI codec driver once with a slight
hope that more vendors will follow the standard, but in reality, the
driver received more and more vendor-specific code. In order to make
the messy code a bit more understandable, this patch splits the HDMI
codec driver into multiple drivers again.
Namely, the vendor-specific code for Intel, AMD and Nvidia are moved
into the own drivers, while we split the common HDMI code to two
drivers, the generic HDMI driver and the simple HDMI driver.
So, now we have:
- The generic HDMI driver (snd-hda-codec-hdmi):
providing the common helpers, also supports Glenfly HDMI codecs and
some other codecs that don't need vendor-specific stuff
- The simple HDMI driver (snd-hda-codec-simplehdmi):
devices with no dynamic PCM assignment and with fixed channels,
mostly used by some other drivers, but this driver alone suffices
for VIA HDMI codec support, too
- Intel HDMI driver (snd-hda-codec-intelhdmi):
bound with i915 / Xe DRM, based on the generic HDMI driver
- AMD/ATI HDMI driver (snd-hda-codec-atihdmi):
optionally bound with radeon / amdgpu DRM, based on the generic HDMI
driver
- Nvidia HDMI driver (snd-hda-codec-nvhdmi);
optionally bound with nouveau DRM, based on the generic HDMI driver
- Legacy Nvidia HDMI driver (snd-hda-codec-nvhdmi-mcp):
for 2ch or 8ch outputs, based on the simple HDMI driver
- Nvidia Tegra HDMI driver (snd-hda-codec-tegrahdmi):
based on the generic HDMI driver
Along with the driver split, the enable_silent_stream module option is
moved to snd-hda-codec-intelhdmi, too, as it's an Intel-specific
feature.
Most of the changes here are just to split and move the code to
different files, as well as to rename/expose the functions that are
commonly used by drivers.
The silent stream handling code is slightly modified for putting the
stuff into Intel driver; now a new callback "silent_stream" is defined
in hdmi_ops, and it's called in silent_stream_enable() and *_disable()
functions. The runtime-PM handling in silent_stream_enable() was
cleaned up, and rather taking the runtime PM refcount in the
silent_stream() callback appropriately, instead.
Other than that, there should be no functional changes.

The snd-hda-codec-realtek driver supports many different codec models
and accumulated lots of quirks. Now let's split it to multiple
modules per probe function, i.e. for ALC260, ALC262, ALC269, etc.
The common code and quirks are provided by the common library module,
snd-hda-codec-realtek-lib now. One drawback of this action is that
many symbols have to be exported. But they are limited with
SND_HDA_CODEC_REALTEK namespace, at least.
This patch tries to be idiomatic and doesn't try to rewrite the
existing code. We can move the codec model-specific code into each
codec driver later.
The HD-audio sub-codec component binding is currently specific to
ALC269, hence the management is moved into alc269.c.
After that, alc_free() became identical with snd_hda_gen_free(), and
it's replaced as a macro just to call snd_hda_gen_free().

Now move the all remaining codec drivers from sound/pci/hda to
sound/hda/codecs subdirectory. Some drivers are put under the further
vendor subdirectory, and the vendor helper code (*_helper.c) are put
under helpers subdirectory. Also the sub-codec drivers are moved under
a different subdirectory, sound/hda/codecs/sub-codecs, for
distinguishing from the main HD-audio codec drivers.
The prefix patch_ and hda_ as well as the suffix _helper are dropped
from file names as they are mostly superfluous.
No functional changes but just file path shuffling.
