Anton Blanchard 0f864ae8b9 Update JTAG TAP controller for Microwatt 
Make a few changes to match what mw_debug expects:

- 6 byte instructions
- IDCODE at 001001
- microwatt debug at 000011

Also change IDCODE to be an IBM ID.

Anton Blanchard fd9350c3b5 First pass at an external JTAG port 
The verilator simulation interface uses the remote_bitbang
protocol from openocd. I have a simple implementation for
urjtag too.
