RFC ARM: S3C24XX: irq move to drivers and first steps to dt

On the way back from Barcelona I've started the move of the common s3c24xx irq-code to drivers/irqchip and also modifications to enable using it in a devicetree context at some point.

So, as I'm also missing the now probably famous tail-lights in this, it would be cool to have some feedback if I'm moving in the right direction here or am thinking wrong somewhere.

The whole endeavour is of course not finished yet, but should not break anything in its current form.

Tested on a s3c2416 based machine.

Heiko Stuebner (4):
ARM: S3C24XX: move s3c24xx-irq to drivers/irqchip
irqchip: s3c24xx: add irq_domains for the interrupt registers
ARM: S3C24XX: irq_data conversion for s3c_irqsub_* functions
ARM: S3C24XX: First part converting irq code to use hwirq
