This patch adds support for the SD/MMC host controller found
on Wondermedia 8xxx series SoCs, currently supported under
arm/arch-vt8500.

A binding document is also included, based on mmc.txt with
additional properties.

clk_{un}prepare is mandatory for platforms using common clock framework.

The previous patch which implemented a DT binding for sdhci-tegra did not
allow all platform data fields to be initialized from DT. The following
were missing:

is_8bit: Implemented by this patch.

pm_flags: Not implemented yet. There are no mainline users of this field.
  I'm not quite sure what it's for, and hence how to represent this
  in DT; the value ends up being assigned to host->mmc->pm_caps.

While we're at it, fix the binding documentation to refer to "SD/MMC"
instead of "eSDHC", since that's the correct name; "eSDHC" was cut/paste
from the Freescale binding docs.
