dmaengine: sirf: clear pending DMA interrupt when DMA terminates
If DMA interrupt comes and is latched by IRQ controller during the execution of dma_terminate_all(), dma_irq routine will be executed after dma terminated, and it will cause kernel panic. We clear DMA interrupts in dma_terminate_all() to avoid this useless interrupt.
