[PATCH v13 01/15] dt-bindings: phy: Add 2500BASE-X and 10GBASE-R

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.

PR increasing phy-type maximum [1].

If this commit could be applied sooner rather than later, I'd appreciate
it. This should help avoid another respin if someone else adds another
phy type.
