[PATCH v3 00/14] Remove platform callbacks from mmc_spi, sh_mmcif and sh_mobile_sdhi drivers

This patch set replaces callbacks to board code with regulators and GPIOs in
the mmc_spi, sh_mmcif and sh_mobile_sdhi MMC drivers.

Most of the required infrastructure is in place already on the drivers side,
except for CD debouncing support in the MMC core and CD/RO GPIOs support in
the mmc_spi driver. The series thus starts with patches 01/14 and 02/14 that
add those features to the MMC core and mmc_spi driver.

Patches 03/14 to 07/14 remove the board callbacks from the ecovec24 and
vision_ep9307 boards. The code has been compile-tested only as I don't have
access to those boards.

Patches 08/14 to 14/14 then proceed to remove the callbacks from the drivers
themselves and from the platform data structures.

Compared to v2, the patches have been rebased on the mmc-next branch from
git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc.git. I've also added
patch 07/14 that removes the .set_pwr() callback from the ag5evm board to avoid
compilation breakage during bisection.

The series interleaves patches for drivers and board files. The ep93xx and
ecovec24 patches have been acked, and the respective ARM subtree maintainers
have indicated that they are fine with the patches going through the MMC tree.
The ag5evm patch is new, but as the ag5evm board is going to be removed in
v3.12, it shouldn't cause any issue.

Chris, could you take the patches in your tree ? I've pushed them to
