Add missing address-cells 0 to the PCI interrupt node to silence W=1
warning:
armada-37xx.dtsi:518.4-521.29: Warning (interrupt_map): /soc/pcie@d0070000:interrupt-map:
Missing property '#address-cells' in node /soc/pcie@d0070000/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)
