Anindam, Lets follow Nico advise -- please ignore my last post on moving it

Arindam,
Could you look at making (Tuning) CMD19 part of the sdhc.ci driver? It flow
is part of the Host Controller and Physical layer specs.
I am not sure that it belongs in core/ as it is transparent to the other
functions and is unclear why it needs to be exposed
adding Nico for comment

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 avai
