AFAIK the CROS_EC is only available on the Chromebook. So move the
corresponding define to the snow config file and include the keyboard
only in this case.
Also the LCD should be protected in the same way, though this seems
to be also valid for the SMDK5250 board.
Unfortunately compilation breaks for the SMDK5250 without the CROS_EC
define, so pull it in for this board too for the time being.
