irqchip/nvic: Convert from handle_IRQ() to handle_domain_irq()

Marc Zyngier · Marc Zyngier · commit 9e027dd979be · 2021-06-10T13:09:19.000+01:00
Given that the nvic driver is fully irqdomain aware, there is no
reason for it to use the arch-specific handle_IRQ(), and it can
be moved over to handle_domain_irq().
