To enable the regulator the VREG_EN pin needs to be either pulled high or left unconnected. This
keeps compatibility with BlueCore2-ROM as the corresponding pin on BlueCore2-ROM was designated
as a not connect pin. In this situation the BlueCore4-ROM regulator is permanently on replicating the
BlueCore2-ROM that has no regulator enable pin.
