amd-xgbe: Add PPS periodic output support
Add support for hardware PPS (Pulse Per Second) output to the AMD XGBE driver. The implementation enables flexible periodic output mode, exposing it via the PTP per_out interface.
The driver supports configuring PPS output using the standard PTP subsystem, allowing precise periodic signal generation for time synchronization applications.
The feature has been verified using the testptp tool and oscilloscope.
