[PATCH 6/7] dmaengine: change the flags of request_irq()

Hi,

The GPMI may have many DMA channels, such as the imx23 has
four DMA channels. All these DMA channels share the same interrupt.
So change the flags from '0' to IRQF_SHARED, else there will be
an EBUSY error returns.

Problem is, that the mxs_dma_int_handler() need to be rewritten
for that since it currently does not support shared interrupts (as you
can easily find out by enabling CONFIG_DEBUG_SHIRQ.
