 *      Frame timestamper for nrf_802154 on the nRF5340 network core.
 *
 *      Frame timestamping is disabled in the project config
 *      (NRF_802154_FRAME_TIMESTAMP_ENABLED 0), so these entry points are
 *      not exercised. They are provided as no-ops so the library links.
 *      A full implementation would subscribe the HP timer (TIMER2)
 *      CAPTURE task to the supplied DPPI channel, mirroring the nRF54L15
 *      port.
