vc/amd/fps/phoenix/platform_descriptors: drop logical-physical mapping
For Phoenix the lane numbers in the DXIO descriptor match the ones in
the schematic, so remove the corresponding text and the table from the
comment on the fsp_dxio_descriptor struct. Since there's no logical to
physical lane number remapping needed for the lanes in the Phoenix DXIO
descriptors, drop the 'logical' from the start_logical_lane and
end_logical_lane fields in the DXIO descriptor and rename those to
start_lane and end_lane.
