Wesley W. Terpstra 0368b6db6b 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
