Pull MMC updates from Chris Ball:
 "MMC highlights for 3.12:

  Core:
   - Support Allocation Units 8MB-64MB in SD3.0, previous max was 4MB.
   - The slot-gpio helper can now handle GPIO debouncing card-detect.
   - Read supported voltages from DT "voltage-ranges" property.

  Drivers:
   - dw_mmc: Add support for ARC architecture, and support exynos5420.
   - mmc_spi: Support CD/RO GPIOs.
   - sh_mobile_sdhi: Add compatibility for more Renesas SoCs.
   - sh_mmcif: Add DT support for DMA channels"
