    Patch from Ben Dooks
    
    A number of small issues with the S3C24XX DMA have
    cropped up, which this patch fixes. These are:
    
      - check wether we can load another buff in start
      - update state handling in s3c2410_dma_lastxfer
      - only reload in irq if channel is not idle
      - more informative timeout errors (add source)
      - do not call request_irq() with irqs locked
      - added waitforstop function
    
    The patch also adds a S3C2410_DMAOP_STARTED for
    the occasions when the driver wants to ensure that
    the DMA system load state is resynced after loading.
