The patch looks OK, but given the module is removable, I think it should be
an overlay. The overlay would enable WiFi + Bluetooth, and all the
peripherals needed to connect them.

That way, if the module is not installed, we avoid confusing the user with
unused peripherals, and avoid having live voltage on an unoccupied header.
