[PATCH v3 6/6] irqchip: s3c24xx: add s3c2450 interrupt definitions

[Heiko Stübner]

The s3c2450 is special in that it shares the cpu identification with the
s3c2416 but provides more interrupts for its additional components.

It also shares the layout of the main interrupt register with the s3c2443
and therefore reuses this definition.

As no non-dt boards are present, the s3c2450 irqs will only be
accessible thru devicetree.
