Fix FPU control bug for div/sqrt

76af15a6ff Fix FPU control bug for div/sqrt 
I was examining a WB-stage control signal instead of a MEM-stage control
signal.  I refactored the code to group the signals together, so that this
sort of bug is less likely going forward.

87a5665e43 axi4: only block writes if SAME master has outstanding reads (#782) 
* axi4: only block writes if SAME master has outstanding reads
* tilelink2: ToAXI4 rename variable
TL uses sources, not IDs like AXI. Keep it less confusing.
* tilelink2: ToAXI4 improve stall circuit delay
Don't bother decoding the AXI ID to compute stall.

5994714970 diplomacy: move manager unification to meta-data only 
Now that PMA circuits already perform address unification, there is
no QoR gained by throwing away the true and complete diplomatic
address+node information. Defer the unification to pretty printing
the DTS address map only.
