Subject: [PATCH] Revert "arm64: dts: zynqmp: Add address-cells property to interrupt controllers"

This reverts commit c6badbd2d321c19d4f55ee56b0ef12bb3352feac.

Long time ago this was discussed with Rob at link below that there is no
need to add address-cells to gpio and interrupt nodes that's why reverting
this patch for ZynqMP.
Also there is no visible DTC warning which was seen in past.
