Merge branch irq/loongarch-of into irq/irqchip-next 



* irq/loongarch-of:
  : .
  : Initial OF support for LoongArch. Funny how it only took
  : *one* release from plumbing ACPI into an unsuspecting
  : architecture to start enabling OF on it. Oh well...
  : .
  irqchip/loongarch-cpu: Fix a missing prototype warning
  dt-bindings: interrupt-controller: add yaml for LoongArch CPU interrupt controller
  irqchip: loongarch-cpu: add DT support
