From: Karol Kolacinski <karol.kolacinski@intel.com>
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.
Fixes: 7cab44f1c35f ("ice: Introduce ETH56G PHY model for E825C products")

From: Karol Kolacinski <karol.kolacinski@intel.com>
Driver always naively assumes, that for PTP purposes, PHY lane to
configure is corresponding to PF ID.
This is not true for some port configurations, e.g.:
- 2x50G per quad, where lanes used are 0 and 2 on each quad, but PF IDs
are 0 and 1
- 100G per quad on 2 quads, where lanes used are 0 and 4, but PF IDs are
0 and 1
Use correct PHY lane assignment by getting and parsing port options.
This is read from the NVM by the FW and provided to the driver with
the indication of active port split.
Remove ice_is_muxed_topo(), which is no longer needed.
Fixes: 4409ea1726cb ("ice: Adjust PTP init for 2x50G E825C devices")
