[PATCH] dt-bindings: interrupt-controller: mediatek,mt6577-sysirq: Drop invalid JSON pointer

[Rob Herring (Arm)]

The $ref "arm,gic.yaml#/properties/#interrupt-cells" doesn't work when
used with another json-schema implementation (rust). The issue is it not
a valid URI due to the 2nd "#" character in the JSON pointer. Though a
"#" is supposed to be valid within a JSON pointer. A possible solution
is to encode the "#" as "%23" instead, but the dtschema tools don't
handle that.

Just avoid all these issues as the $ref only resolves to a "const: 3"
schema and specify it directly.
