Typo: binding. Also missing capital letter.

This does not make sense. You cannot have two fallbacks. Old binding was
here confusing or even incorrect, so please fix this in the conversion.
It's fine to do the conversion and change, just explain what is done
here and why.

-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].
