dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".

Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
exynos5250-cros-common.dtsi was meant for sharing common pieces across
ChromeOS devices. This turned out premature, as several devices ended up
in the common file that are not common after all. Since the remaining
common ChromeOS pieces are fairly minor, exynos5250-cros-common.dtsi
was requested to be merged into the Snow device tree, sharing only the
keyboard controller for now. This may be re-evaluated as both mature.

The device tree sent upstream for exynos5250-snow encoded the search
key as CAPSLK. However in all ChromeOS kernels it is L_META. One can
certainly have long debates about which it ought to be, but I'm
proposing setting it to L_META because:
* That's how _all_ ChromeOS kernels do it and will do it.
* There is no L_META key on the board, so it's nice to have.
* For those people who really want it to be caps lock, they can use
xmodmap or somesuch.

This dts file is based on the Snow dts file in the Chromium OS kernel
tree with the following changes:
* Some details have been updated to match the exynos5250-smdk5250.dts
file from linux-next (as of c11068538994430547722dc9fb515a0ceefd5cb9).
* This file doesn't include references to hardware whose upstream
support isn't quite there yet. That includes most i2c devices.
Note that most i2c busses have been included with no devices.
The Snow dts file is mostly just an include of the "cros5250" dts file
which describes a class of similar boards. Support for other boards has
not yet been send upstream.
With this file and a change to use UART3 for serial output I can:
* Boot to a command line using either SD or EMMC as a root filesystem
* See the power button and lid switch using evtest.
