mem: Add support for handling CMOs in the MSHRs
To add support for cache maintenance operations (CMOs) in the MSHRs,
this change adds the following functionality:
- If a CMO request hits in the MSHRs, we deferred as we can't
coalesce it with any other requests.
- When we promote any deferred targets, we promote them in order and
stop if we encounter a CMO request. If the CMO request is at the
beginning of the deferred targets list it will be the only promoted
target.
