<div class='commit-subject'>ARM64: dts: meson-gxbb-odroidc2: fix GbE tx link breakage</div><div class='commit-msg'>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.
