[PATCH 33/34] ASoC: Intel: sof_sdw: Add quirk for optional codec speakers

[Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>]

From: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxx>

Some codecs have speaker drivers that may or may not be used in a
given system. Add a quirk (SOF_CODEC_SPKR) that defines if a system
uses the codec speaker, this is kept generic such that any codec
with such a speaker DAI can reuse the quirk.

For implementation of this, add a quirk field into the
sof_sdw_dai_info structure. This field is not used to specify
if a system uses a particular quirk, that is still done through
the sof_sdw_quirk variable, this field is used to flag a DAI as
conditional on a certain quirk. This means the DAI will only be
included in the card if sof_sdw_quirk and the DAI quirk field have
a matching set bit.
