Some I3C hardware will report error when incorrect length is received from
device. GETMXDS CCC are availble in 2 formats; without turnaround time (format
1) and with turnaround time (format 2). There is no mechanics to determine which
format is supported by device. In case sending GETMXDS CCC format 2 resulted
failure, try sending GETMXDS CCC format 1 instead.
