Pull MMC updates from Ulf Hansson:
 "MMC core:
   - Optimize boot time by detecting cards simultaneously
   - Make runtime resume default behavior for MMC/SD
   - Enable MMC/SD/SDIO devices to suspend/resume asynchronously
   - Allow more than 8 partitions per card
   - Introduce MMC_CAP2_NO_SDIO to prevent unsupported SDIO commands
   - Support the standard DT wakeup-source property
   - Fix driver strength switching for HS200 and HS400
   - Fix switch command timeout
   - Fix invalid vdd in voltage switch power cycle for SDIO

  MMC host:
   - sdhci: Restore behavior when setting VDD via external regulator
   - sdhci: A couple of changes/fixes related to the dma support
   - sdhci-tegra: Add Tegra210 support
   - sdhci-tegra: Support for UHS-I cards including tuning support
   - sdhci-of-at91: Add PM support
   - sh_mmcif: Rework dma channel handling
   - mvsdio: Delete platform data code path"
