arm64: Tell irq work about self IPI support
commit 3631073659d0aafeaa52227bb61a100efaf901dc upstream.
ARM64 irq work self-IPI support depends on __smp_cross_call to point to
some relevant IRQ controller operations. This information should be
available after the call to init_IRQ().
Lets implement arch_irq_work_has_interrupt() accordingly.
