mmc_test with mmc_spi

From: Thomas Kunze

Hi Pierre,

I wrote a small hack to be able to use the mmc_test driver on mmc-spi host. You or somebody else might find it useful.
All test but "Correct xfer_size at write (start failure)", "Correct xfer_size at read (start failure)" and "Correct xfer_size
at write (midway failure)" passed.
I'm not sure what these tests try to do and how they do it, so I don't know if my modifcations of mmc_test, my spi driver or the
mmc-spi driver are responsible.

It would be great if you could provide some insight.

Regards,
Thomas
