From: Anton Vorontsov <avorontsov@xxxxxxxxxxxxx>
This patch simply adds sdhci node to the device tree.
We specify clock-frequency manually, so that eSDHC will work without
upgrading U-Boot. Though, that'll only work for default setup (1500 MHz)
on new board revisions. For non-default setups, it's recommended to
upgrade U-Boot, since it will fixup clock-frequency automatically.
