Bus clash detected error can be seen on many SoundWire devices on check-suspend-resume-with-playback-25.sh and check-suspend-resume-with-capture-25.sh test (SOF v1.6.1 release test report ID 828)

Ideally, HW will be recovered from bus clash. But it could also be a sign. So create a issue to track it.

Recipe:
Kernel: topic/sof-dev 38e180a
SOF : master 90955de

Note that Bus clash detected doesn't contain any error key words, so CI didn't fail with the Bus clash detected log before.
It means that the issue could already exist for a while.

@RanderWang @plbossart FYI

    @bardliao should the bus clash ignore_str filter be removed in sof-test/tools/sof-kernel-log-check.sh? See https://github.com/thesofproject/sof-test/pull/529/files

    Yes, we should not ignore "Bus clash"
