   28 - interrupt-controller : Identifies the node as an interrupt controller
   29 - #interrupt-cells : Use the same format as specified by GIC in arm,gic.txt.
   30 - reg: Physical base address of the intpol registers and length of memory
   31   mapped region. Could be multiple bases here. Ex: mt6797 needs 2 reg, others
   32   need 1.

   34 Example:
