37865fe91582 is v2.6.37-rc4~24^2~7 so it sounds like this patch
should also be applied to 3.0.y.
Here's a straightforward backport to account for the lack of
v3.1-rc1~321^2~77 ("mmc: sdhci: make sdhci-pltfm device drivers self
registered") and v3.1-rc1~125^2^2~5 ("mmc: sdhci-esdhc-imx: get rid of
the uses of cpu_is_mx"). Sensible?

commit b89152824f993a9572b47eb31f4579feadeac34c upstream.
This was broken by me in 37865fe91582582a6f6c00652f6a2b1ff71f8a78
("mmc: sdhci-esdhc-imx: fix timeout on i.MX's sdhci") where more
extensive tests would have shown that read or write of data to the
card were failing (even if the partition table was correctly read).
