net: lan743x_ptp: convert to ktime_get_clocktai_ts64

arndb · davem330 · commit 0b3e776e2e80 · 2018-08-19T10:56:40.000-07:00
timekeeping_clocktai64() has been renamed to ktime_get_clocktai_ts64()
for consistency with the other ktime_get_* access functions.

Rename the new caller that has come up as well.

Question: this is the only ptp driver that sets the hardware time
to the current system time in TAI. Why does it do that?
