Updated git commit as follows and Applied to
dpdk-next-net-mrvl/for-next-net. Thanks
net/cnxk: add SoC specific PTP timestamp read
Timestamp resolution for an incoming and outgoing packets
is different for CN10k and CN9K. Added SoC specific
callback to retrieve timestamp in correct format
when read by application.
