Ensure that unused I2C controllers are not activated, causing problems due
to inappropriate pinmuxing or similar, by marking the controllers as
disabled by default and requiring boards to explicitly enable those that
are in use.

Rather than requiring each board to explicitly disable the SPI controllers
it is not using instead require boards to enable those that they are using.
This is less work overall since normally at most one of the controllers is
in use and avoids issues caused by inappropriate pinmuxing.

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.

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.
