stmmac: intel: Update PCH PTP clock rate from 200MHz to 204.8MHz

Browse source

Current Intel platform has an output of ~976ms interval
when probed on 1 Pulse-per-Second(PPS) hardware pin.

The correct PTP clock frequency for PCH GbE should be 204.8MHz
instead of 200MHz. PSE GbE PTP clock rate remains at 200MHz.
