From: Charles Keepax <ckeepax@opensource.cirrus.com>

Add support for the optional speaker output on the cs42l43, this uses
the new SOF_CODEC_SPKR quirk to conditional include the speaker DAI
link. It is worth noting that currently no systems are included that
utilise this feature, but the feature is added as several systems are on
the horizon. As part of this SOF_SDW_MAX_DAI_NUM must be increased, it
is currently 3 but cs42l43 will now have 4 DAI links. This value is
increased to 8 to give some head room for future devices.
