LoongArch: dts: loongson-2k2000: Add default interrupt controller address cells

Browse Source 
Add missing address-cells 0 to the Local I/O, Extend I/O and PCH-PIC
Interrupt Controller node to silence W=1 warning:

  loongson-2k2000.dtsi:364.5-49: Warning (interrupt_map): /bus@10000000/pcie@1a000000/pcie@9,0:interrupt-map:
    Missing property '#address-cells' in node /bus@10000000/interrupt-controller@10000000, using 0 as fallback

Value '0' is correct because:
1. The LIO/EIO/PCH 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)
