net: phy: Add support for 1PPS out and external timestamps

The perout function is used to generate a 1PPS signal, synchronized
to the PHC. This is accomplished by a using the hardware oneshot
functionality, which is reset by a timer.

The external timestamp function is set up for a 1PPS input pulse,
and uses a timer to poll for temestamps.

Both functions use the SYNC_OUT/SYNC_IN1 pin, so cannot run
simultaneously.
