* include/rtems/libio.h: Internally use a union of an unsigned64
and major/minor device so we don't get into trouble shifting.
The h8300 seemed to be impossible to remove warnings otherwise.
Eventually the structure definition of a dev_t might be better anyway.
* include/sys/ioccom.h: Added casts to remove warnings on 16 bit
targets.
