[PATCH 2/2] ARM: dts: imx6qdl: Add default GIC address cells

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

  imx6qdl.dtsi:281.4-284.29: Warning (interrupt_map): /soc/pcie at 1ffc000:interrupt-map:
    Missing property '#address-cells' in node /soc/bus at 2000000/gpc at 20dc000, using 0 as fallback

Value '0' is correct because:
1. GPC interrupt controller children are only power domains,
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)
