If we had an info device, it would fall into the same category as info
cpu or info registers. It duplicates the functionality of the gdbstub
but it provides a convenience interface for those who don't have gdb
connected.
Since there isn't really an obvious way to expose the device state via
gdb without using Rcmd and a new monitor command, the whole debate seems
academic :-)
