net/ice/base: save user provided PHY config

After the transition from cable-unplug to cable-plug events, FW will
clear the set-phy-cfg data, sent by user. Thus, we will need to
cache these info.
1. The submitted data when set-phy-cfg is called. This info will be used
later to check if FW clears out the PHY info, requested by user.
2. The FC, FEC and LinkSpeed, requested by user. This info will be used
later, by device driver, to construct the new input data for the
set-phy-cfg AQ command.
