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.

We need to use the i2c-arbitrator to talk to any of the devices on i2c
bus 4 on exynos5250-snow so that we don't confuse the embedded
controller (EC).  Add the i2c-arbitrator to the device tree.  As we
add future devices (keyboard, sbs, tps65090) we'll add them on top of
this.

The arbitrated bus is numbered 104 simply as a convenience to make it
easier for people poking around to guess that it might have something
to do with the physical bus 4.

The addition is split between the cros5250-common and the snow device
tree file since not all cros5250-class devices use arbitration.
