Pull MMC updates from Chris Ball:
 "MMC highlights for 3.14:

  Core:
   - Avoid get_cd() on cards marked nonremovable

  Drivers:
   - arasan: New driver for controllers found in e.g. Xilinx Zynq SoC
   - dwmmc: Support Hisilicon K3 SoC controllers
   - esdhc-imx: Support for HS200 mode, DDR modes on MX6, runtime PM
   - sdhci-pci: Support O2Micro/BayHubTech controllers used in laptops
     like Lenovo ThinkPad W540, Dell Latitude E5440, Dell Latitude E6540
   - tegra: Support Tegra124 SoCs"
