This is a temporary fix for ethernet with kernels 5.4.7+
It reverts the following change: https://patchwork.ozlabs.org/patch/1213121/
which disabled mdio init for most of the boards except NanoPi M4(V2)
or NanoPC T4 which have proper device tree definition for mdio/phy.
The proper fix will be to add phy device tree node for boards that miss
it.
