[media] s5p-mfc: Replace bank1/bank2 entries with an array
Internal MFC driver device structure contains two entries for keeping
addresses of the DMA memory banks. Replace them with the dma_base[] array
and use defines for accessing particular banks. This will help to simplify
code in the next patches.
