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. Rename rmn_0 to phy_0 and remove rmn_1 and rmn_2 as E82X HW does not support it. Rename eth56g_phy_1 to phy_0_peer.
