arm64: dts: ti: k3-j721s2: Add default PCI interrupt controller address cells 



Add missing address-cells 0 to the PCI interrupt node to silence W=1
warning:

  k3-j721s2-main.dtsi:1431.3-1434.29: Warning (interrupt_map): /bus@100000/pcie@2910000:interrupt-map:
    Missing property '#address-cells' in node /bus@100000/pcie@2910000/interrupt-controller, using 0 as fallback

Value '0' is correct because:
1. GIC interrupt controller does not have children,
2. interrupt-map property (in PCI node) consists of five components and
   the fourth component "parent unit address", which size is defined by
   '#address-cells' of the node pointed to by the interrupt-parent
   component, is not used (=0)
