[ARM] 4270/2: mach-s3c2443/irq.c off by one error in dma irqs
This patch corrects an error when demuxing the DMA irq's DMA1 was used as a base and this should have been DMA0. Without this fix we do not process DMA0 irq's and the system effectively locks up in a loop trying the process the irq it never can.
