Subject: [PATCH] fpga: e320/n3xx: dts: Fixed PHY mode for 1G connections

Without this change, kernel 6.12 generates the following warning:

nixge 40000000.ethernet (unnamed net_device) (uninitialized): fixed link full duplex 1000Mbps not recognised

With the change, the link is correctly detected as 1G:

nixge 40000000.ethernet sfp0: configuring for fixed/gmii link mode
