irqchip: Move IRQCHIP_DECLARE macro to include/linux/irqchip.h
At the moment the IRQCHIP_DECLARE macro is only declared locally in drivers/irqchip/irqchip.h. It prevents from using it directly in arch/* directories whenever irqchip drivers only exist there, which happens in a few cases (e.g. arc, arm, microblaze and mips). This patch makes the macro to be globally defined, i.e. in include/linux/irqchip.h, and thus usable for arch-specific declarations of irqchip drivers. In this way, it is very similar to what clocksource does (ie CLOCKSOURCE_OF_DECLARE is defined in include/linux/clocksource.h). For now, this patch only moves the declaration of the macro IRQCHIP_DECLARE to the global header 'include/linux/irqchip.h' and make 'drivers/irqchip/irqchip.h' include 'include/linux/irqchip.h'. Later, other patches will get rid of 'drivers/irqchip/irqchip.h' and modify all the impacted irqchip drivers.
