The device is registered all right from MFD code, but the module won't
be loaded automatically from user-space even with the right
MODULE_ALIAS() for sub-nodes unless we define the
MODULE_DEVICE_TABLE().

Besides: the DT bindings define the compatible for sub-nodes already.
We should probably conform to that.
