Merge tag 'mmc-v4.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull another MMC update from Ulf Hansson:
 "Here's a second pull request for MMC for v4.10.

  As a matter of fact it's only one change that moves some mmc files
  around. I thought it was a good idea to get this into v4.10, as it
  gives us a nice and fresh base for v4.11. Summary:

  MMC core:

   - Move files from the card directory to the core directory to enable
     future clean-ups of the generic mmc header files and interfaces"
