ahb: replace defective crossbar with a functional one
...
The previous crossbar had the following bugs:
1. a bursting master could be preempted
the AHB-lite spec requires a slave receive the entire burst
2. a waited master could be replaced
the AHB-lite spec requires haddr/etc to remain unchanged
3. hmastlock did no ensure exclusive access
atomic operations could be pre-empted

It appears to never be used, and clutters things. The new invariant is
