Merge tag 'mmc-v4.6-rc3' of git://git.linaro.org/people/ulf.hansson/mmc

Pull MMC fixes from Ulf Hansson:
 "Here are a couple of mmc fixes intended for v4.6 rc4.

  Regarding the fix for the regression about mmcblk device indexes.  The
  approach taken to solve the problem seems to be good enough.  There
  were some discussions around the solution, but it seems like people
  were happy about it in the end.

  MMC core:
   - Restore similar old behaviour when assigning mmcblk device indexes

  MMC host:
   - tegra: Disable UHS-I modes for Tegra124 to fix regression"
