From: Roy Franz <redacted>
SDP representors do not support hardware timestamping. The current
implementation of otx2_get_ts_info incorrectly advertises hardware
timestamping capabilities and a PHC index to userspace for these
interfaces.
Fix this by checking if the device is an SDP representor and returning
the default software timestamping capabilities instead.
