arm-soc: device tree conversions, part 2

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
or pinctrl changes submitted earlier.
Merge branch 'drivers/mmc' into next/dt2

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.
