db76ff2d86 axi4: Deinterleaver must gather R also for single ID 
In order to guarantee that a complete R can be sent without
sinking B, the Deinterleaver must do its job even on AXI-Lite.

8fc27b0bf2 axi4: IdIndexer; a single ID does NOT imply no response interleaving 
Some slaves may never send R until you process their B.
Thus, while there is no read response interleaving, there
is still interleaving between R and B, which breaks AXI4ToTL.

4847c32599 tilelink: ToAXI4 - must interlock till last beat 
AXI4 makes no guarantee that bursts are handled atomicly.
Thus, you could be part-way through a read burst and suddenly
a write cuts ahead and is visible later, violating FIFO.
