Give Rocket priority over DTIM TL port

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.

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.
