Merge branch irq/modular-irqchips into irq/irqchip-next

* irq/modular-irqchips:
  : .
  : Update a set of irqchip drivers to be build as modules.
  :
  : This includes an Amlogic and multiple Broadcom drivers, triggering
  : a cascade of other changes (MIPS arch code, symbols being exported,
  : config changes)
  : .
