coreplex: CacheBlockOffsetBits was wrong!
...
This bug is ancient. I don't understand how it never mattered before.
Anyway, in processors with a custom CacheBlockBytes, this value is wrong!
The symptom is that TL1 components end up missing high address bits.
This causes, for example, a system to jump to 0 instead of RAM.
I don't understand how this very serious bug did not cause problems before.

regression: disable ComparatorL2Config for now
...
This tests atomics against the L2. However, we don't have an L2 yet so this
is hitting the broadcast hub, which does not support these operations.
