This series fixes a race condition that may result in the output clock

Part of the device initialization aligns the rising edge of the output
clock to the internal 1 PPS clock. If the system APLL and DPLL is not
locked, then the alignment will fail and there will be a fixed offset
between the internal 1 PPS clock and the output clock.

Some PTP hardware clocks have a write phase mode that has
