From: Siddharth Vadapalli <s-vadapalli@ti.com>
The CPSW9G instance of the CPSW Ethernet Switch supports USXGMII mode
with MAC Ports 1 and 2 of the instance, which are connected to ENET
Expansion 1 and ENET Expansion 2 slots on the EVM respectively, through
the Serdes2 instance of the SERDES.
Enable CPSW9G MAC Ports 1 and 2 in fixed-link configuration USXGMII mode
at 5 Gbps each.
