ARC: [SMP] unify cpu private IRQ requests (TIMER/IPI)
The current cpu-private IRQ registration is ugly as it requires need to
expose arch_unmask_irq() outside of intc code.
So switch to percpu IRQ APIs:
-request_percpu_irq [boot core]
-enable_percpu_irq [all cores]
Encapsulated in helper arc_request_percpu_irq()
