Coverage and readability improvements to LRUUpdate logic
...
The genvar stuff was switched to readable names to make it easier
to understand for the first time. In the LRUUpdate logic for loop,
a special case was added for simpler logic in the case of the root
node, to hit coverage.

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.

Exclude (FlushStage & SetValidWay) condition for RO caches
...
Spent a long time trying to find a way to see if this condition was
possible, only to become relativly convinced that it isn't.
Basically, since RO cache writes only happen after a long period of
stall for the bus access, there's no way a flushD can be active
at the same time as a RO cache write. TrapM causes a FlushD, but
interrupts are gated by the "commited" logic and the exception
pipeline stalls.
I feel like its worth keeping the logic to be safe
so I've chosen to exclude it rather than explicitely remove it.
