This adds cros_ec to exynos5420-peach-pit and exynos5800-peach-pi, including: * The keyboard * The i2c tunnel * The tps65090 under the i2c tunnel * The battery under the i2c tunnel To add extra motivation, it should be noted that tps65090 is one of the things needed to get display-related FETs turned on for pit and pi. Note that this relies on a few outstanding changes: * Needs (spi: s3c64xx: fix broken "cs_gpios" usage in the driver) and (spi: s3c64xx: for DT platofrms always get the chipselect info from DT node) to work properly and match the documented bindings.
