Cliff Brake b6018958a5 pxamci: enable DMA for write ops after CMD/RESP
With the PXA270 MMC hardware, there seems to be an issue of
data corruption on writes where a 4KB data block is offset
by one byte.

If we delay enabling the DMA for writes until after the CMD/RESP
has finished, the problem seems to be fixed.
