The KSZ8463 supports periodic outputs but doesn't handle them in the same way as the other KSZ switches. To add proper support for the KSZ8463, a dedicated ksz8463_ptp_restart_perout() function needs to be created. This function will use the same request initialization as the common ksz_ptp_restart_perout() function. Extract the inialization into a dedicated function so it can be used later by the KSZ8463 support.
