media: staging: imx: don't use GFP_DMA when calling dma_alloc_coherent()
dma_alloc_coherent() allocates the DMA buffer with the device's addressing
limitation in mind; the DMA core picks the zone from the device's coherent
DMA mask and ignores GFP_DMA passed by the caller. Remove the redundant
GFP_DMA flag.
