Remove FlushStage Logic from CacheLRU
...
For coverage.
LRUWriteEn is gated by FlushStage in cache.sv,
so removing the signal completely avoids future confusion.
Update cache.sv to reflect cacheLRU edit.

make Cache Flush Logic dependent on !READ_ONLY_CACHE
...
read-only caches do not have flush logic since they do not have to
deal with dirty bits.

remove ClearValid from cache
...
The cachefsm hardwired ClearValid logic to zero.
This signal might've been added to potentially add extra functionality
later. Unless that functionality is added, however, it negatively
impacts coverage. If the goal is to maximize coverage, this signal
should be removed and only added when it becomes necessary.
