octeontx2-nicvf: Add PTP hardware clock support to NIX VF
This patch adds PTP PHC support to NIX VF interfaces. This enables
a VF to run PTP master/slave instance. PTP block being a shared
hardware resource it is recommended to avoid running multiple
PTP instances in the system which will impact the PTP clock
accuracy.
