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/>

Along with the dependency patches on next-20140623, tested keyboard on
Peach-Pi board.
Tested-by: Tushar Behera <[email protected]>
Some comments below.

I would suggest we add similar labels to fet1, fet3, fet4, fet5 and fet6
also. That way it would be easy to reference them in subsequent DT nodes.
Same comment for Peach-Pi dts file too.

OK. I added it to all the regulators in tps65090. That'll probably
be useful for Javier in his max77802 work.

Thanks, in fact I did add both tps65090_dcdc1 and tps65090_dcdc2 labels to be
able to use these regulators as supply for some of the max77802 regulators.
Will rebase on top of this.
