ncr5380: Implement NCR5380_dma_xfer_len and remove LIMIT_TRANSFERSIZE macro
Follow the example of the atari_NCR5380.c core driver and adopt the NCR5380_dma_xfer_len() hook. Implement NCR5380_dma_xfer_len() for dtc.c and g_NCR5380.c to take care of the limitations of these cards. Keep the default for drivers using PSEUDO_DMA. Eliminate the unused macro LIMIT_TRANSFERSIZE.
