There are too many logs on startup, e.g.

[ 8811.851497] cdns_fill_msg_resp: 2 callbacks suppressed
[ 8811.851497] intel-sdw intel-sdw.0: Msg Ack not received
[ 8811.851498] intel-sdw intel-sdw.0: Msg Ack not received
[ 8811.851499] intel-sdw intel-sdw.0: Msg Ack not received
[ 8811.851499] intel-sdw intel-sdw.0: Msg Ack not received
[ 8811.851500] intel-sdw intel-sdw.0: Msg Ack not received
[ 8811.851500] intel-sdw intel-sdw.0: Msg Ack not received
[ 8811.851502] intel-sdw intel-sdw.0: Msg ignored for Slave 0
[ 8811.851503] soundwire sdw-master-0: No more devices to enumerate

We can skip the 'Msg Ack not received' since it's typical of the
enumeration end, and conversely add the information on which command
fails.
