Because pbio(4) only exists on i386. Hence, all other platforms now
have <sys/pbioio.h> that serves no purpose and can only cause
autoconfiguration (ala autoconf) getting confused. Since pbioio.h
refers to hardware, it nature is MD, even though the definitions
(types and interfaces) may appear MI. So, <machine/bpioio.h> seems 
like a good place.
