The auto cmd settings bits should be cleared before sending new commands
or we may receive command timeout error for normal commands due to wrongly

e.g. we receive CMD13 timeout error due to ACMD23 is wrongly enabled

The code sequence:
	dev->dma_mask = &dev->coherent_dma_mask;
	dev->coherent_dma_mask = dma_mask;
bypasses the architectures check on the DMA mask.  It can be replaced
with dma_coerce_mask_and_coherent(), avoiding the direct initialization
of this mask.
