84d856d1e5 busybear: allow testbench to ignore lack of MMU for now

a good thing to be doing

If it is, we're at 1M instructions!

01b1b1705d Busybear: next week of updates 
- move parsed instructions out of git, to /courses/e190ax/busybear_boot
 - parsed first 1M instructions, and now parse from split GDB runs
 - now at about 230k instructions, can't progress further for now since atomic instructions
   aren't implemented yet

f1768ee50b Busybear: start checking CSRs 
scounteren and mcounteren are currenly manually deleted from the CSRs list
(see slack channl #linux-bringup)

and 3 of the CSRs referenced are skipped because of weird locations for them

oh and this doesn't check their initial state, just their changing. This could be a problem
