Update irqbalanced

[Jookia]

The novena irqbalanced port includes changes to balance i.MX6 interrupts. Port these to a newer irqbalance. Here's a quick and dirty patch I did a long time ago that kind of shows what needs to be done, based on top of irqbalance's git commit c63839ce3615e5430f6d549d75cb3e4e474306ea
