This patch enbles use of the basic PIO devices as part of the NULL build. Although it might seem counter intuitive to have a PIO device without being able to execute a driver, this change enables us to break a device class hierarchy into an ISA-agnostic part, and an ISA-specific part, without requiring multiple-inheritance. The ISA-agnostic base class is a PIO device, but does not make use of the port.
