[PATCH v2 2/2] dt-bindings: gpio: aspeed,sgpio: Specify #interrupt-cells

[Andrew Jeffery <andrew@codeconstruct.com.au>]

Squash warnings such as:

    arch/arm/boot/dts/aspeed/aspeed-ast2500-evb.dtb: sgpio@1e780200: '#interrupt-cells' does not match any of the regexes: 'pinctrl-[0-9]+'

Also, mark #interrupt-cells as required. The kernel devicetrees already
specified it where compatible nodes were defined, and u-boot pulls in
the kernel devicetrees, so this should have minimal practical impact.
