Allows drivers to define more fine grained features for devices, not strictly depending on assumptions we can make depending on the implemented vfuncs. We keep this per class but could be in theory moved to each instance. In any case, added an utility function to initialize it in the way we can ensure that we've a consistent way for setting them across all the devices.
