lint: clean up a couple of width fixes in JTAG DTM, and add missing
...
default case to DM acmd state machine. Also remove unnecessary clear
of JTAG DR shifter on TAP reset state, which saves a bit of logic. Two
width mismatches are left unfixed in the DTM (the ones with shifts)
because they bizarrely increase area by 100 LUT4s when fixed.

Fix 3 minor Debug Module bugs:
...
- sbdata0 should ignore writes when sbbusyerror or sberror is set
- All sbaddress0 writes and sbdata0 accesses should set
sbbusyerror if sbbusy is set
- sbaddress should not increment if access gets bus error

Two minor DM bugs:
