Even though these aren't parsed by the MMC driver, make clear that
they're required by the OF core. (Also, a few typo fixes.)

Now that we have common bindings for MMC, rewrite the individual
bindings to inherit from mmc.txt and describe their differences.

Pull arm-soc device tree conversions (part 2) from Olof Johansson:
"These continue the device tree work from part 1, this set is for the
tegra, mxs and imx platforms, all of which have dependencies on clock

Pull arm-soc driver specific updates from Olof Johansson:
"These changes are specific to some driver that may be used by multiple
boards or socs. The most significant change in here is the move of

the generic iommu subsystem."

Changes in the dt2 branch move stuff around that gets changed
in the drivers/mmc branch. I chose a non-obvious resolution by
adding the new bus-width property into all the tegra sdhci device
nodes.

This patch unifies the current DT MMC bindings documentation and code,
adds generic MMC DT bindings documentation, and updates .dts files for
consistency.

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.
