ASoC: hdac_hda: fix HDA patch loader support

The array size is irrelevant with SNDRV_CARDS. dev_index is from
codec address and the available codec number is HDA_MAX_CODECS.
Also, hda_pvt->fw is for a temporary use, no need to add a new extra
field in hdac_hda_priv{}.

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.

Call to snd_hda_codec_build_controls() is delayed for HDMI/DP HDA

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.
