  When cmd->opcode == MMC_SEND_TUNING_BLOCK, the SDHCI_TRANSFER_MODE
should also be kept

change in V1:
Keeping the SDHCI_TRANSFER_MODE when cmd->opcode == MMC_END_TUNING_BLOCK

change in V2:
add the mmc_op_tuning interface to judge if the opcode is tuning CMD

change in V3:
cancel the redundant code
