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.

Conflicts:
	arch/arm/boot/dts/tegra-cardhu.dts
	arch/arm/boot/dts/tegra-harmony.dts
	arch/arm/boot/dts/tegra-ventana.dts
