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

update busybear testbench to conform to new structure
...
aaaaaaaaaaaaaaaaaahhhh so many changes
also the testbench now uses another internal signal,

busybear: simulate first 10k instructions
...
I know we need to add CSR checking sometime soon
Also I'm a bit sketpical this is all working properly, and that no new bugs
were uncovered from 1k instrs to 10k instrs
