Clearfog GTR connects eth2 / serdes 1 to a 2.5Gbps capable ethernet
switch port. Linux already configures a fixed-link at speed 2500 from
device-tree.
Upgrade serdes 1 rate to 3.125Gbps to support a 2.5Gbps link.
Additionally add comments documenting each serdes' function of clearfog
gtr, which are shared with clearfog pro.
