Several architectures select GENERIC_IRQ_MULTI_HANDLER and branch to handle_arch_irq() without performing any entry accounting. Add a generic wrapper to handle the common irqentry work when invoking handle_arch_irq(). Where an architecture needs to perform some entry accounting itself, it will need to invoke handle_arch_irq() itself. In subsequent patches it will become the responsibilty of the entry code to set the irq regs when entering an IRQ (rather than deferring this to an irqchip handler), so generic_handle_arch_irq() is made to set the irq regs now. This can be redundant in some cases, but is never harmful as saving/restoring the old regs nests safely.
