It is not really the SOF CI but the users. it looks like all codecs
using SDCA infra is affected and will fail to probe audio on boot.
I did not has time to fully debug it, but how the currect system works
is that we don't and cannot know the DAI name of an SDCA function, they
are parsed and created by parsing the DiSCO table and they will have
FUNCTION_NAME.index, then index is a running number.
If the table has different ordering than for example UAJ can be
UAJ.1/2/3/etc.

The current way is to wait for the codecs (SDCA stack) to probe and
create the DAIs then we check and adjust the dai_link in the sof_sdw
machine driver.
If the SDCA function probes after the machine driver then we will never
have match for the dai link.

At the moment I don't see a reasonably quick workaround for this, but I
let Bard and Charles to comment.

Users of PTL are likely to be affected as their design seams to be
closely identical with most of them having cs42l45 codec for Jack, which
is SDCA only.
