This patchset adds PTP support for CN10K silicon, specifically
to workaround few hardware issues and to add 1-step mode.

Patchset overview:

Patch #1 returns correct ptp timestamp in nanoseconds captured
         when external timestamp event occurs.

Patch #2 adds 1-step mode support.

Patch #3 implements software workaround to generate PPS output properly.

Patch #4 provides a software workaround for the rollover register default
         value, which causes ptp to return the wrong timestamp.
