Fix for issue #343
Created by: silabs-oysteink
LSU response filter is now outputting what type of load/store is associated with a bus error. Also routing the bus_resp through the filter for cleaner code. Controller now gets two bits from the load_store_unit, one for qualifying an NMI and one for signaling if it is for a load or store.
