The RocketChip JTAGIO exposes the TDO.enable signal, which shouldn't go off chip.
This adds a JTAGChipIO which we use as the type of the JTAG IOs for ChipTop.

Type of change: bug fix

Impact: rtl change

LGTM. Was this a change in the rocket-chip interface or just a bug in our initial implementation?
