vt82c686: Make vt82c686-pm an I/O tracing region

Browse source 
Previously just an empty RAM region was mapped on realize, now we add
an empty io range logging access instead. I think the pm timer should
be hooked up here but not sure guests need it. PMON on fuloong2e sets
a base address but does not seem to enable region; the pegasos2
firmware pokes some regs but continues anyway so don't know if
anything would make use of these facilities. Therefore this is just a
clean up of previous state for now and not intending to fully
implement missing functionality which could be done later if some
guests need it.
