Convert the old text binding to new YAML.

While at it, make some changes to the binding:
- The version numbers are not documented publicly. The version also does
not change programming interface. Remove it until it's really needed.
- A few clocks are missing in old binding file. Add them to match the real
hardware.

-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].
