simple non-concurrent I/D WB can be done in node but doesn't do anything useful; to use both,
need to allow at least 2 load credits and add second reload buffer
reset vector is now a `define, but still must hit the pre-configured erat entries; it would require
cp3_nia_q to be loaded from inputs, and would have to override the FFFFFFFC entry RA during erat init por sequence.
