Add additional information returned to userland by the device querying

functions.  We add pnpinfo, locationinfo, devflags (the newbus flags
on the device), flags (the flags that device_get_flags returns) and
state to the list of things we return.

pnpinfo and locationinfo are place holders at the moment that will be
filled in by the device's parent (optionally).  Userland programs will
likely use this information from time to time and take appropriate
actions.

Improvements to devinfo to follow.
