[U-Boot] [PATCH v4 3/4] Initialize second PHY on OpenRD-Client and OpenRD-Ultimate

[Clint Adams]

Though the OpenRD-Base only has one gigabit Ethernet port,
both the OpenRD-Client and OpenRD-Ultimate each have two.

On the Ultimate, the PHY addresses are consecutive, but
on the Client they are not.
