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.
