PatchTrack

All S3C24XX arches share the same interrupt registers and basic handling principles but the individual interrupts differ quite a lot between all the arches. This series therefore tries to unify this a bit by abstracting the irq handling and enabling the arches to simply provide a structure describing its individual interrupts. With this declarative approach it should also be (hopefully) easy to move this to devicetree later. For the initial transformation (in patch 1) I gave up on trying to do this in individual steps, so the patch might be a bit bumpy to read, but the new irq code does provide the exactly same interrupts and handlers as the old code. This also means that the unconverted arches shouldn't feel any difference at all. I've only included the s3c2416 and s3c2443 interrupts for now, as the s3c2416 is my main development platform and the s3c2443 is so very similar. But the other arches use the same mechanics so conversion should be quite easy later. As it seems to be the policy for drivers/irqchip that drivers there should not contain platform-hooks or pollute the namespace with custom init functons, the irq code stays in plat-s3c24xx for now.
