This switches the mxcmmc driver to use the dmaengine API. Unlike
the old one this one is always present in the tree, even if no DMA
is implemented, hence we can remove all the #ifdefs in from the driver.
The driver automatically switches to PIO mode if no DMA support or no
suitable channel is available.

The patch looks good to me, but shouldn't you also add a Kconfig
dependency or select on CONFIG_DMA_ENGINE? I don't see where that
gets set.

I've pushed this to mmc-next now, but please do reply to Arnd's Kconfig
question.

Thanks,
