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.
