ARM64: dts: meson-gxbb-odroidc2: fix GbE tx link breakage
OdroidC2 GbE link breaks under heavy tx transfer. This happens even if the MAC does not enable Energy Efficient Ethernet (No Low Power state Idle on the Tx path). The problem seems to come from the phy Rx path, entering the LPI state. Disabling EEE advertisement on the phy prevent this feature to be negociated with the link partner and solve the issue.
