net: jr2: Fix Serdes6G configuration
Sometimes no traffic was getting out on the ports, the root cause was
a wrong configuration of the Serdes6G, which is used on jr2 pcb111.
This patch fixes this issue by applying the correct configuration.
Fixes: 5e1d417bec92ac ("net: Add MSCC Jaguar2 network driver.")
