Give Rocket priority over DTIM TL port

1bac2cbdf8 Give Rocket priority over DTIM TL port
The TL port can easily starve the processor, even at only 20% utilization,
because of a bad interaction with the pipeline.  Giving the processor
static priority is OK in practice, since <50% of instructions are loads
and stores in typical workloads.  Even if it executes 100% loads and stores,
it must eventually encounter an I$ miss, taken branch, or exception, so
even malicious code can't permanently starve the TL port.

acecc407a5 HellaCache: we do NOT really support probe below the block size!
If we did, you would somehow have to retain ownership of the
unprobed parts of the block, in case they happened to be dirty.

fa412246b3 Error: don't be an exception wrt. caching
Prior to this PR, the error device was allowed to be cached by
multiple actors despite never probing any of them. This is a
pretty unusual set of properties that has caused us trouble
several times now in the past.

Let's instead put the Error device into one of two very well
established categories: a straight-up MMIO device or a tracked
memory region.
