DECON nodes according to documentation have only one port so it is OK.
DSI has two ports, but since on all Exynos platforms DSI panels/bridges
are subnodes of ExynosDSI the 2nd port is not used.
So if there will be a platform with DSI panel/bridge controlled via I2C,
it should be reverted., but this is theoretical problem.
