Hisilicon Fast Ethernet MAC controller

Required properties:
- compatible: should contain one of the following version strings:
	* "hisilicon,hisi-femac-v1"
	* "hisilicon,hisi-femac-v2"
	and the soc string "hisilicon,hi3516cv300-femac".
- reg: specifies base physical address(s) and size of the device registers.
  The first region is the MAC core register base and size.
  The second region is the global MAC control register.
- interrupts: should contain the MAC interrupt.
- clocks: A phandle to the MAC main clock.
- resets: should contain the phandle to the MAC reset signal(required) and
	the PHY reset signal(optional).
- reset-names: should contain the reset signal name "mac"(required)
	and "phy"(optional).
- phy-mode: see ethernet.txt [1].
- phy-handle: see ethernet.txt [1].
- hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given.
	The 1st cell is reset pre-delay in micro seconds.
	The 2nd cell is reset pulse in micro seconds.
	The 3rd cell is reset post-delay in micro seconds.

The MAC address will be determined using the optional properties
defined in ethernet.txt[1].
