We are cleaning up the implicit presence of module.h; these guys are
some of the people who just assume it will be there.  Call it out
explitly for those that really need it.

Fix clock rate setting in the mxs-mmc driver. Previously, if div2 was 0
then the value for TIMING_CLOCK_RATE would have been 255 instead of 0.
The limits for div1 (TIMING_CLOCK_DIVIDE) and div2 (TIMING_CLOCK_RATE+1)
were also not correctly defined.

Can easily be reproduced on mx23evk: default clock for high speed sdio
cards is 50 MHz. With a SSP_CLK of 28.8 MHz default), this resulted in
an actual clock rate of about 56 kHz.  Tested on mx23evk.

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.
