dt-bindings: gpio: Convert Arm PL061 to json-schema
Convert the Arm PL061 GPIO controller binding to json-schema format. As I'm the author for all but the gpio-ranges line, make the schema dual GPL/BSD license.

-ARM PL061 GPIO controller
-
-Required properties:
-- compatible : "arm,pl061", "arm,primecell"
-- #gpio-cells : Should be two. The first cell is the pin number and the
- second cell is used to specify optional parameters:
- - bit 0 specifies polarity (0 for normal, 1 for inverted)
-- gpio-controller : Marks the device node as a GPIO controller.
-- interrupts : Interrupt mapping for GPIO IRQ.
-- gpio-ranges : Interaction with the PINCTRL subsystem.
