iavf: Implement settime64 with -EOPNOTSUPP

Browse Source 
ptp_clock_settime() assumes every ptp_clock has implemented settime64().
Stub it with -EOPNOTSUPP to prevent a NULL dereference.

The fix is similar to commit 329d050bbe ("gve: Implement settime64
with -EOPNOTSUPP").

Fixes: d734223b2f ("iavf: add initial framework for registering PTP clock")
