irq: remove handle_domain_{irq,nmi}() Now that entry code handles IRQ entry (including setting the IRQ regs) before calling irqchip code, irqchip code can safely call generic_handle_domain_irq(), and there's no functional reason for it to call handle_domain_irq(). Let's cement this split of responsibility and remove handle_domain_irq() entirely, updating irqchip drivers to call generic_handle_domain_irq(). For consistency, handle_domain_nmi() is similarly removed and replaced with a generic_handle_domain_nmi() function which also does not perform any entry logic. Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire when they were called in an inappropriate context. So that we can identify similar issues going forward, similar WARN_ON_ONCE() logic is added to the generic_handle_*() functions, and comments are updated for clarity and consistency.

irqchip: Prepare for local stub header removal The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so the local irqchip.h became an empty shell, which solely includes include/linux/irqchip.h Include the global header in all irqchip drivers instead of the local header, so we can remove it.

irqchip: Add support for TI-NSPIRE irqchip This patch adds support for the interrupt controllers found in some TI-Nspire models. FIQ support was taken out to simplify the driver code and may be added in later. Since Linux on this platform doesn't really use FIQs, this wasn't really that important in the first place.
