[Manjunathappa, Prakash]

Patch moves emif header file appropriately as a part preparation to move emif
driver from arch/arm/mach-davinci/ to drivers/mfd folder.
There by it isolates modifications in emif interface depicting as platform code
change.

Patch series are based on the discussion and concerns expressed in
davinci-linux-open-source community. Here is the link for the same:
