LoongArch: Make arch_irq_work_has_interrupt() true only if IPI HW exist 



After commit 7c405fb3 ("rcu: Use an intermediate irq_work to
start process_srcu()"), Loongson-2K0300/2K0500 fail to boot. Because
IRQ_WORK need IPI but Loongson-2K0300/2K0500 don't have IPI HW.

So make arch_irq_work_has_interrupt() return true only if IPI HW exist.
