ptp: netc: only enable periodic pulse event interrupts for PPS
The periodic pulse event interrupts are used to register the PPS events
into the system, so it is only applicable to PTP_CLK_REQ_PPS request.
However, these interrupts are mistakenly enabled in PTP_CLK_REQ_PEROUT
request, so fix this error.
