Subject: [PATCH] dt-bindings: PCI: Add missing "#address-cells" to interrupt controllers

An interrupt-controller node which is the parent provider for
"interrupt-map" needs an "#address-cells" property. This fixes
"interrupt_map" warnings in new dtc.

Signed-off-by: Rob Herring (Arm) <robh@...nel.org>

PCI maintainers, Please ack, I'll take this with the dtc update for 
6.18.
