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.
