[PATCH iwl-net] i40e: set supported_extts_flags for rising edge

[Przemyslaw Korba <przemyslaw.korba@intel.com>]

The i40e driver always supported only rising edge detection, so
advertise PTP_RISING_EDGE, and PTP_STRICT_FLAGS to ensure the
PTP core properly validates user requests.

Fixes: 7c571ac57d9d ("net: ptp: introduce .supported_extts_flags to ptp_clock_info")
