we have a Dell ADL laptop which has sdw audio, but there is no camera
and no internal digital mic in this machine, the current soc driver
can't work on this machine, it will load a wrong tplg without this patch,
and the speaker and headset couldn't work.

Backport one patch from upstream.

Boot the patched kernel on the machine, check dmesg, it loads the
correct tplg, and test speaker and headset, all work well.

[Where problems could occur]
If it could introduce regression, it will be on the sdw codec matching
for adl machines, then it will make the driver load wrong tplg and make
output device and input device not work anymore. But this possibility
is very low, we already tested the patch on some dell adl machines, no
regression found.
