mxs-dma : move the mxs dma.h to a more common place
Move the header to a more common place.
The mxs dma engine is not only used in mx23/mx28, but also used
in mx50/mx6q. It will also be used in the future chips.
Rename it to mxs-dma.h, and create a new folder include/linux/fsl/ to
store the Freescale's header files.
change mxs-dma driver, mxs-mmc driver, gpmi-nand driver, mxs-saif driver
to the new header file.
