mtd: rawnand: gpmi: don't use GFP_DMA when calling dma_alloc_coherent()

Browse Source 
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.  Use GFP_KERNEL instead
so the allocation may reclaim as usual for probe-time allocations.
