Pull MMC updates from Ulf Hansson:
 "MMC core:
   - Add support for Marvell SD8787 Wifi/BT chip
   - Improve UHS support for SDIO
   - Invent MMC_CAP_3_3V_DDR and a DT binding for eMMC DDR 3.3V mode
   - Detect Auto BKOPS enable bit
   - Export eMMC device lifetime information through sysfs
   - First take to slim down the public mmc headers to avoid abuse
   - Re-factoring of the mmc block device driver to prepare for blkmq
   - Cleanup code for the mmc block device driver
   - Clarify and cleanup code dealing with data requests
   - Cleanup some code by converting to ida_simple_ functions
   - Cleanup code dealing with card quirks
   - Cleanup private and public mmc header files

  MMC host:
   - Don't rely on public mmc headers to include non-mmc related headers
   - meson: Add support for eMMC HS400 mode
   - meson: Various cleanups and improvements
   - omap_hsmmc: Use the proper provided busy timeout from the core
   - sunxi: Enable new timings for the A64 MMC controllers
   - sunxi: Improvements for clock management
   - tmio: Improvements for SDIO interrupts
   - mxs-mmc: Add CMD23 support
   - sdhci-msm: Enable HS400 enhanced strobe mode support
   - sdhci-msm: Correct HS400 tuning sequence
   - sdhci-acpi: Support deferred probe
   - sdhci-pci: Add support for eMMC HS200 tuning mode on AMD
   - mediatek: Correct the implementation of card busy detection
   - dw_mmc: Initial support for ZX mmc controller
   - sh_mobile_sdhi: Enable support for eMMC HS200 mode
   - sh_mmcif: Various cleanups and improvements"
