ice: Introduce ETH56G PHY model for E825C products

E825C products feature a new PHY model - ETH56G.

Introduces all necessary PHY definitions, functions etc. for ETH56G PHY,
analogous to E82X and E810 ones with addition of a few HW-specific
functionalities for ETH56G like one-step timestamping.

It ensures correct PTP initialization and operation for E825C products.
