board: solidrun: clearfog: fix serdes 1 / eth2 speed for clearfog gtr
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.
