[PATCH v2 0/2] board: solidrun: clearfog gtr: add serdes configuration
Add missing configuration options for clearog gtr serdes:
1. select between sata and pci-e for serdes 0 2. configure serdes 2 for 2.5Gbps link with managed switch

Sincerely,
Clearfog GTR has an assembly option for a SATA connector, CON18. It shares the serdes with mini-pcie connector CON3.
Add new kconfig option to select betweenata and pci, defaulting to pci as it was previously configured in board-file.
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 network link on Clearfog GTR.

Additionally add comments documenting each serdes' function of clearfog gtr, which are shared with clearfog pro.
