arm64: dts: rockchip: add basic mdio node to px30

Using snps,reset-* properties for handling the phy-reset is deprecated
and instead a real phy node should be defined that then contains the
reset-gpios handling.

To facilitate this, add the core mdio node under the px30's gmac, similar
to how the other Rockchip socs already do this.
