Fix an issue in plat_irq_dispatch due to which it can call do_IRQ with a PIC irq that is not mapped. When a per-cpu interrupt and a PIC interrupt are both active, the check 'eirr & PERCPU_IRQ_MASK' will be true, but the interrupt in 'i' will be the number of the PIC interrupt. In this case, we will call do_IRQ on the PIC interrupt without mapping it with nlm_irq_to_xirq(). Fix this by using __ffs64 instead of __ilog2_u64 and using the interrupt number instead of mask to identify per-cpu interrupts.
