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.

Earlier we just waited for the first thread of the CPU to come online before proceeding to wake up others. Update it to wait for all the CPUs in the core. This will be useful when the boot-up is slow, like while debugging or when running in a simulator.
