Hisilicon hix5hd2 gmac controller

Required properties:
- compatible: should be "hisilicon,hix5hd2-gmac".
- reg: specifies base physical address(s) and size of the device registers.
  The first region is the MAC register base and size.
  The second region is external interface control register.
- interrupts: should contain the MAC interrupt.
- #address-cells: must be <1>.
- #size-cells: must be <0>.
- phy-mode: see ethernet.txt [1].
- phy-handle: see ethernet.txt [1].
- mac-address: see ethernet.txt [1].
- clocks: clock phandle and specifier pair.

- PHY subnode: inherits from phy binding [2]
