cool :-)

As you might have seen I tried to move it to drivers/irqchip in the past and 
it seems only drivers using the new irqchip init stuff should go there now.

So I left it where it is for now, to see how far I get with the modifications 
first. So, as drivers/irqchip is out of the question for now, should we move 
it to mach-s3c24xx in the meantime?

As I still need to also send the redone devicetree patches on top of this 
series, I could do the move there to a location you prefer :-)
