ARM: dts: zynq: drop address cells from GIC node

This is likely a copy-and-paste error from the
ARM GIC documentation, that has already been fixed.

address-cells should have been set to 0, as with the size
cells. As having those properties set to 0 is the
same thing as not specifying them, drop them completely.
