This adds some modes necessary for Lynx 10G support. 2500BASE-X, also
known as 2.5G SGMII, is 1000BASE-X/SGMII overclocked to 3.125 GHz, with
autonegotiation disabled. 10GBASE-R, also known as XFI, is the protocol
spoken between the PMA and PMD ethernet layers for 10GBASE-T and
10GBASE-S/L/E. It is typically used to communicate directly with SFP+
modules, or with 10GBASE-T phys.

A corresponding update to the schema for phy-type[1] will be needed. A 
GH PR or patch to devicetree-spec@vger.kernel.org is fine.
