* include/confdefs.h, include/rtems/config.h, include/rtems/io.h,
optman/no-io.c, src/exinit.c, src/io.c: Added a device driver
register/unregister interface to allow device drivers to be
installed and removed at runtime. This means you do not need devices
present in the device table when you build.
