Subject: [Intel-wired-lan] [PATCH iwl-net] ice: Recalibrate PHY after
settime64 on E825-C

From: Maciek Machnikowski <redacted>

The PHY on E825-C requires recalibration after large jumps of the
system time. Add missing PHY recalibration also on E825-C.

Fixes: 7cab44f1c35f ("ice: Introduce ETH56G PHY model for E825C
products")
