Log:
  MFC r231589: Add a sysctl to report the firmware build number.
  
    Some older firmware versions have issues that can be worked around by
    avoiding certain operations.  Add a sysctl dev.aac.#.firmware_build to
    make it easy for scripts or userland tools to detect the firmware
    version.
