Subject: [PATCH 05/11] irqchip/irq-brcmstb-l2: Switch to IRQCHIP_PLATFORM_DRIVER

Allow the user selection and building of this interrupt controller
driver as a module since it is used on ARM/ARM64 based systems as a
second level interrupt controller hanging off the ARM GIC and is
therefore loadable during boot.
