mmc: dw_mmc: Regression fix for non-IDMAC DMA
3ec7699d3bb1b0ee7 ("mmc: dw_mmc: Add support for pre_req and post_req")
broke non-IDMAC DMA, because dw_mci_pre_dma_transfer() is valid only if
using internal DMA. In case of using other DMA it returns -ENOSYS. It
prevents the DMA operations. This patch makes dw_mci_pre_dma_transfer()
effective in all DMA cases again.
