mtd: nand: marvell: Fix missing memory allocation modifier 

The function marvell_nfc_init_dma() allocates a DMA buffer without the
GFP_KERNEL modifier, that triggers this warning:
"marvell_nfc_init_dma() error: no modifiers for allocation."

Fix this by using (GFP_KERNEL | GFP_DMA) instead of only GFP_DMA as the
probe happens in non-interrupt context.
