ice: Add correct PHY lane assignment

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.
