  Don't attach special devices in the order they appear in the AML tree.
  If the embedded controller exists before the sysresource devices, for
  example, it will be attached first.  Instead, let the normal device
  order function work as we first desired. [1]
  There still remained a problem where we couldn't allocate resources in
  acpi0 that were passed up by the sysresource pseudo-devices.  These
  devices had to probe/attach first to give their resources to acpi, then
  acpi would allocate them before probing/attaching other devices.  To
  work around this, we attach them from acpi_sysres_alloc().  A better
  approach would be to implement multi-pass probe/attach in newbus but
  that's a much bigger task.
