8b58327fa4 axi4: conversion from TL does not need beatBytes (#1051) 
We used to pack the addr_lo into user bits. We don't do that anymore.
There is thus no need to waste those bits, nor to pass that arg.

5886025b1a sbus => pbus: 2 buffers should already be enough 
There is a buffer on the sbus backside.
There is a buffer on the pbus frontside.

Between them is only an AtomicAutomata.
That should be enough for most designs.
