[RFC] remove bus_memio.h and bus_pio.h

The bus_memio.h and bus_pio.h for a micro-optimization depend on the
implementation of the bus_space on i386 and amd64, so they are
meaningless files on the other archs.  I'd like to remove a MD part
like this from MI drivers at least.

I think that a increasing performance by using this method is very
trivial on recent machines.  If there is not strong objection, I'll
remove bus_{mem,p}io.h and related code from all archs.

Comments?
