Pull MMC updates from Chris Ball:
 "MMC highlights for 3.8:

  Core:
   - Expose access to the eMMC RPMB ("Replay Protected Memory Block")
     area by extending the existing mmc_block ioctl.
   - Add SDIO powered-suspend DT properties to the core MMC DT binding.
   - Add no-1-8-v DT flag for boards where the SD controller reports
     that it supports 1.8V but the board itself has no way to switch to
     1.8V.
   - More work on switching to 1.8V UHS support using a vqmmc regulator.
   - Fix up a case where the slot-gpio helper may fail to reset the host
     controller properly if a card was removed during a transfer.
   - Fix several cases where a broken device could cause an infinite
     loop while we wait for a register to update.

  Drivers:
   - at91-mci: Remove obsolete driver, atmel-mci handles these devices
     now.
   - sdhci-dove: Allow using GPIOs for card-detect notifications.
   - sdhci-esdhc: Fix for recovering from ADMA errors on broken silicon.
   - sdhci-s3c: Add pinctrl support.
   - wmt-sdmmc: New driver for WonderMedia SD/MMC controllers."
