ice: Fix quad registers read on E825

Quad registers are read/written incorrectly. E825 devices always use
quad 0 address and differentiate between the PHYs by changing SBQ
destination device (phy_0 or phy_0_peer).

Add helpers for reading/writing PTP registers shared per quad and use
correct quad address and SBQ destination device based on port.
