Merge tag 'mmc-4.2-rc3' of git://git.linaro.org/people/ulf.hansson/mmc

Pull MMC fixes from Ulf Hansson:
 "Here are some mmc fixes intended for v4.2 rc4.

  Note, most of the changes are for the sdhci-esdhc-imx controller,
  which also required us to modify some related DTS files.  Those
  changes have been acked by the SoC maintainer.
