[PATCH 4/6] irq: add a new generic IPI handling code to irq core

Add a generic mechanism to dynamically allocate an IPI. With this change the user can call irq_reserve_ipi() to dynamically allocate an IPI and use the associate virq to send one to 1 or more cpus. No irq_get_irq_hwcfg() as I hope we can provide an implementation without hardware specific part.
