uboot-mediatek: fix BT-R320 Ethernet mode

The CPU port between the MT7981 and MT7531 runs at 2.5 Gbps, but the U-Boot
device tree configures it as SGMII at 1 Gbps. This leaves Ethernet unable
to exchange packets despite an active physical link.

Use 2500base-x and a 2500 Mbps fixed link, matching the Linux device tree.
