genirq: Make early_irq_init() print out more informative



The printk in early_irq_init() is cryptic and badly formatted:

  NR_IRQS:33024 nr_irqs:968 16

The last number is the number of preallocated interrupts, so add a prefix
to it:

  NR_IRQS: 33024, nr_irqs: 968, preallocated irqs: 16

Cleanup the formatting for better readability as well.
