+Hisilicon Hi6220 GPIO controller bindings

+Required properties:
+ - compatible: "arm,pl061","arm,primecell"
+ - gpio-controller: Marks the device node as a GPIO controller.
+ - #gpio-cells: Should be 2. See gpio.txt in this directory for a
+ description of the cells format.
+ - interrupt-controller: Mark the device node as an interrupt controller

Why do you need extra binding document here as the compatible is same as
[1] ? You can extend that if required and add example there IMO.
