irqchip/xilinx: Add explicit dependency on OF_ADDRESS

Commit b84dc7f0 ("irqchip/xilinx: Remove microblaze+zynq
dependency") relaxed the dependencies on the Xilinx interrupt controller
to be OF only, but some OF architectures (s390 for example) do not
support OF_ADDRESS and so a build of the driver will result in undefined
references to of_iomap/iounmap and friends.
