Passing IEC 61937 encapsulated compressed audio at bitrates over 6.144
Mbps (i.e. more than a single 2-channel 16-bit 192kHz IEC 60958 link)
over HDMI requires the use of HBR Audio Stream Packets instead of Audio
Sample Packets.
Enable HBR mode when the stream has 8 channels and the Non-PCM bit is
set.
If the audio converter is not connected to any HBR-capable pins, return
-EINVAL in prepare().

The behavior of Nvidia HDMI codec regarding the pin-detection unsol events
is based on the old HD-audio spec, i.e. PD bit indicates only the update
and doesn't show the current state. Since the current code assumes the
new behavior, the pin-detection doesn't work relialby with these h/w.
This patch adds a flag for indicating the old spec, and fixes the issue
by checking the pin-detection explicitly for such hardware.

This patch adds the device id for Nvidia GT220 cards to the nvhdmi
driver. I have tested it and confirmed it to be working.

Create patch_hdmi.c to hold common code from intelhdmi and nvhdmi.
For now the patch_hdmi.c file is simply included by patch_intelhdmi.c
and patch_nvhdmi.c, and does not represent a real codec.
There are no behavior changes to intelhdmi. However nvhdmi made several
changes when copying code out of intelhdmi, which are all reverted in
this patch. Wei Ni confirmed that the reverted code actually works fine.

In the commit f0613d5752
ALSA: hda - Add full rates/formats support for Nvidia HDMI
the flag LIMITIED_RATE_FMT_SUPPORT was set as default, as I forgot
to clear before commit.
Let's enable all formats/rates as default.

Allow Nvidia HDMI to support more possible sample rates and formats.
At best, the really supported rates and formats should be determined
together with the negotiation with the HDMI receiver, but it's currently
not implemented yet (Nvidia stuff seems incompatible with HDMI 1.3
standard in this regard). As a compromise, we enable all bits, assuming
that all recent devices do support such rates/formats.

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
