An attempt to fix the random poking in legacy io space...

ask for permissions before poking at io ports.  this affects
detect_and_report_winbond() and detect_and_report_smsc().

Its unclear what port number is returned in show_parconfig_winbond(), so
just request the region as well and free the probing region.
