This adds the mmc host driver for Freescale MXS-based SoC i.MX23/28. The driver calls into mxs-dma via generic dmaengine api for both pio and data transfer. Thanks Chris Ball for the indentation patch.

This option is selected by drivers running on big endian hosts

implements a hardware byte swapper using a 32-bit datum.

accessed in sizes other than the datum size.
