Ahb tweaks ( #50 )
...
* ahb: handle tlDataBytes==1 and tlDataBeats==1 gracefully
I only now learned that chisel does not handle 0-width wires properly
and that log2Up and log2Ceil differ on 1. Fix-up code to handle this.
* ahb: optionally disable atomics => optimize to nothing
Trust the compiler the compiler to optimize away unused logic.

This code is correct, but Chisel2 erroneously flags it as a Chisel3
compatibility error because it looks like Vec(Reg) when factor=1.
