Subject: [PATCH net-next v18 05/10] net: netdevsim: ptp_mock: Convert to
netdev_ptp_clock_register
The hardware registration clock for net device is now using
netdev_ptp_clock_register to save the net_device pointer within the PTP
clock xarray. netdevsim is registering its ptp through the mock driver.
It is the only driver using the mock driver to register a ptp clock.
Convert the mock driver to the new API.
