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

Simplify TileLink Narrower
...
It's not necessary to use addr_beat to determine where to put the Grant
data. Just stripe it across all lanes.
This also gets rid of a dependence on addr_beat in Grant. If we move
towards a regime where TileLink is only narrowed, not widened, we may
be able to drop the field altogether.
