[PATCH v2] ARM: dts: Add cros_ec to exynos5420-peach-pit and exynos5800-peach-pi

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. See
<https://patchwork.kernel.org/patch/4346701/> and
<https://patchwork.kernel.org/patch/4346711/>
