ice: add rx timestamp tracepoint for debugging
Add ice_rx_hwtstamp trace event to help debug PTP rx timestamp issues.
The trace captures cached_time, ts_high, and the extended ts_ns value in
ice_ptp_get_rx_hwts().
Enable with:
echo 1 > /sys/kernel/debug/tracing/events/ice/ice_rx_hwtstamp/enable
cat /sys/kernel/debug/tracing/trace_pipe
