Pull MMC updates from Ulf Hansson:
 "There are no updates for the MEMSTICK subsystem this time. But note
  that I am also carrying a patch from the pinctrl tree, which has been
  shared through an immutable branch.

  Summary:

  MMC core:
   - Convert to reasonable timeouts for all CMD6 commands (updates for
     BKOPS, CACHE_FLUSH and INAND_CMD38_ARG_EXT_CSD) for eMMC

   - Add gpiod_toggle_active_low() API
   - Consolidate slot-gpio code by using gpiod_toggle_active_low()

  MMC host:

   - Consolidate pintctrl code by using pinctrl_select_default_state()
   - mmci: Support any block sizes for SDIO for some variants
   - mmci: Enable reset control for stm32_sdmmc
   - mmc_spi: Toggle SPI_CS_HIGH polarity rather than hard-coding it
   - renesas_sdhi: Add support for the r8a77961 variant
