I suppose if your driver/subsystem is critical for system boot, like powering a regulator or something that has a critical purpose, a select is probably more appropriate here. If this is just exposing non-critical devices, I would go with a depends on/default at the driver Kconfig level.
This is just how I see things, others would definitively have a different view.
