mmc: dw_mmc: Remove dma_ops from struct dw_mci_board

It does take dma_ops from struct dw_mci_board, but we immediately
re-assign it from either dw_mci_idmac_ops or dw_mci_edmac_ops in
dw_mci_init_dma(). That means it's never used now, or has been
broken for a long time without noticed. It seems no drivers need
it, so remove it now.
