Documentation: dt: gpio-omap: Move interrupt-controller from #interrupt-cells description
The binding documentation for the OMAP GPIO controller has the
"#interrupt-cells" property listed before "#interrupt-controller"
property but its description after.
This is confusing so we move "#interrupt-cells" after the
"interrupt-controller" property so is followed by its description.
While being there, change the properties order to be consistent with
Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
and Documentation/devicetree/bindings/gpio/gpio.txt.
According with these docs, the order of the properties for a gpio-omap
device node should be:
gpio-controller;
#gpio-cells = <2>;
interrupt-controller;
#interrupt-cells = <2>;
