dt-bindings: interrupt-controller: arm,gic: Support two address and size cells

It should be valid for a GICv2m node, child of a GICv2 node, to use two
cells per reg address and size. The QEMU virt device-tree currently
fails validation because the schema imposes a single address and size
cell. Amend the rule.
