What we need to do is add a new jtag_device_def_type entry for the
can128 in jtagio.cc. The only non-obvious part is the
jtag_device_desc_type field which is defined in jtag.h (I tried to
extensively comment this structure to make adding new devices less
painful and less reliant on getting the info from Atmel).

We may be able to intuit the information we need without snooping the
serial line.
