net: phy: Add interface types for 50G and 100G
Add support for 802.3cd based interface types 50GBASE-R and 100GBASE-P.
This choice in naming is based on section 135 of the 802.3-2022 IEEE
Standard.
In addition it is adding support for what I am referring to as LAUI
which is based on annex 135C of the IEEE Standard, and shares many
similarities with the 25/50G consortium. The main difference between the
two is that IEEE spec refers to LAUI as the AUI before the RS(544/514) FEC,
whereas the 25/50G use this lane and frequency combination after going
through RS(528/514), Base-R or no FEC at all.
