Tomasz Maciej Nowak db014428b1 mvebu: armada-37xx: remove ethernet alias patch
This patch has been added with initial support for ESPRESSObin board and
mistakenly it affects all boards with this SoC. Drop this patch since
the aliases are now in upstream dts for ESPRESSObin. If any boards are
relying on this, please add the respective alias to that board dts.

Certain SFP modules (most notably Nokia GPON ones) first check
connectivity on 1000base-x, and switch to 2500base-x afterwards. This
is considered a quirk so the phylink switches the interface to
2500base-x as well.
However, after power-cycling the uDPU device, network interface/SFP module
will not work correctly until the module is re-seated. This patch
resolves this issue by forcing the interface to be brought up in
2500base-x mode by default.
