In the dts{i}, yes. But we don't want to break systems in the field
with "mrvl,..." compatible strings. Therefore, at least the drivers
need an extra compatible string to support "mrvl,...".

If it had just been since v3.9, it'd be different/simpler. However,
several vendors have opted to use kernels newer than v3.5, which makes
this scenario a real possibility.
