  Rx PHY timer init value is not same as primary timer init value when
power up which will lead Rx timestamp always have big gap compared
with PTP timestamp. This patch adds PHC init time in initializing PTP
hardware clock.

Fixes: 646dcbe6c701 ("net/ice: support IEEE 1588 PTP")
Cc: stable@dpdk.org
