Nasti Puts: decode wmask to determine addr_byte() and op_size()
...
This change is TL0 specific; TL2 knows the op_size, and can use
this to do a much simpler one-hot decode of the address.

tilelink: wmask was double the width it should be
...
When amo_offset = UInt(0), UIntToOH(amo_offset) = "b01", not b"1".
This meant that the amo wmask was double wide, making wmask() fat.

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.
