We need priv->ptp_caps to hold a structure and not just a pointer, because we use container_of in the various PTP callbacks. Therefore, the sja1105_ptp_caps structure declared in the global memory of the driver serves no further purpose after copying it into priv->ptp_caps. So just populate priv->ptp_caps with the needed operations and remove sja1105_ptp_caps.
