HDAC_LAST_DAI_ID is last index id, pcm buffer array size should
be +1 to avoid out of bound access.

3fd63658ca ASoC: Intel: Drop hdac_ext usage for codec device creation
To make snd_hda_codec_device_init() the only constructor for struct
hda_codec instances remaining tasks are:

1) no struct may wrap struct hda_codec as its base type
2) bus drivers (skylake and sof) which are the current hdac_ext users
   need to be adjusted to make use of newly added codec init and exit
   routines instead
3) as bus drivers (skylake and sof) are to be responsible for creating
   codec device and assigning it to hdac_hda_priv->codec,
   hdac_hda_dev_probe() has to be freed of that job

To keep git bisect happy, all of these in made in one-go.

Use hdac_to_hda_codec() instead of container_of().

No functional change intended.

ASoC: hdac_hda: Update hdac hda dai table to include intel-hdmi-hifi4
TGL supports more than three HDMI Dai's. So, update hdac_hda_dais table
to include 4th DAI.

Without this patch, we saw the below error in TGL DUT:

ASoC: hdac_hda: add support for HDMI/DP as a HDA codec
Handle all HDA codecs using same logic, including HDMI/DP.

Call to snd_hda_codec_build_controls() is delayed for HDMI/DP HDA
devices. This is needed to discover the PCM device numbers as
defined in topology.

ASoC:hdac_hda:use correct format to setup hda codec
The current implementation of the hdac_hda codec results in zero-valued
samples on capture and noise with headset playback when SOF is used on
platforms with an on-board HDaudio codec. This is root-caused to SOF
using be_hw_params_fixup, and the prepare() call using invalid runtime
fields to determine the format.

This patch moves the format handling to the hw_params() callback, as
done already for hdac_hdmi, to make sure the fixed-up information is
taken into account but keeps the codec initialization in prepare() as
the stream_tag is only available at that time. Moving everything in the
prepare() callback is possible but the code is less elegant so this
two-step solution was chosen.

The solution was tested with the SST driver with no regressions, and all
the issues with SOF playback and capture are solved.

ASoC: hdac_hda: add asoc extension for legacy HDA codec drivers
This patch adds a kernel module which is used by the legacy HDA
codec drivers as library. This implements hdac_ext_bus_ops to enable
the reuse of legacy HDA codec drivers with ASoC platform drivers.
