JTAG 2 DMI interface written, based instead on Staf Chips4Makers TAP
code, well written, understandable enough to drop a DMI FSM on it.
quick unit test shows that c4m jtag IDCODE csn be read, dmi interface
works and wishbone works too.
tomorrow i will link into litex sim, i am not sure whether to replace
the DMI debug code already in place, it was real handy.
also drop in JTAG into ls180soc and see how that goes.
