Remove parameters for some things that aren't parameterizable
...
Heads up @colinschmidt and @ccelio. I'm removing these because
they are ISA constants and so are not truly parameters, so the
parameter place is not the place for them. Since BOOM and Hwacha
both depend on rocket, you should be able to obtain them by
instantiating/extending rocket.HasCoreParameters.

Fix L2 Writeback deadlock issue
...
The deadlock condition occurs when the acquire tracker attempts to
request a writeback while the writeback unit is still busy and a
voluntary release for the block to be written back is coming in.
The voluntary release cannot be accepted because it conflicts with the
acquire tracker. The acquire tracker can't merge the voluntary release
because it is waiting to send the writeback. The writeback can't
progress because the release it is waiting on is behind the voluntary
release.
The solution to this is to break the atomicity guarantee between the
acquire tracker and the writeback unit. This allows the voluntary
release tracker to take the voluntary release before the writeback unit
accepts the conflicting request. This causes a potential race condition
for the metadata array. The solution to this is to have the writeback
unit re-read the metadata after accepting a request.
