[PATCH] arm64: dts: rockchip: rk356x: add ethernet aliases

[Philipp Puschmann]

Providing ethernet aliases solves a subtle problem for the rk3568. The
bus_id used for the sysfs directory name of the mdio. Without ethernet
alias the bus_id is always 0 and so creating the sysfs directory for the
second mdio fails with a duplicate filename error and by this the setup
of the second ethernet port fails too.

Note: The alias numbering is inverted as gmac1 comes from more generic
rk356x.dtsi but gmac0 comes from specialised rk3568.
