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

[Michal Simek]

The commit 3eb619b2f7d8 ("scripts/dtc: Update to upstream version
v1.6.0-11-g9d7888cbf19c") updated dtc version which also contained DTC
commit
"81e0919a3e21 checks: Add interrupt provider test"
where reasons for this checking are mentioned as
"A missing #address-cells property is less critical, but creates
ambiguities when used in interrupt-map properties, so warn about this as
well now."

That's why add address-cells property to gic and gpio nodes to get rid of
this warning.

I was grepping DTSes in the kernel and most of them list it as 0.
In gicv3 case where its node is added it needs to be filled property that's
why also non 0 values are there.
Definitely please let me know if 0 is not the right value here.

Based on https://lore.kernel.org/r/cover.1606917949.git.michal.simek@xilinx.com/
