net: sparx5: Fix invalid timestamps
Bit 270-271 are occasionally unexpectedly set by the hardware. This issue
was observed with 10G SFPs causing huge time errors (> 30ms) in PTP. Only
30 bits are needed for the nanosecond part of the timestamp, clear 2 most
significant bits before extracting timestamp from the internal frame
header.
Fixes: 70dfe25cd866 ("net: sparx5: Update extraction/injection for timestamping")
