  Log:
  Explain what we're doing in pcic_pci_shutdown a little better.  Try to
  explain the subtle side effects that are going to happen and why we go
  ahead and ack the interrupt source.  This stuff is tricky to get
  right.
  
  Also, emperical tests have shown that doing a shutdown in attach to be
  ineffectual, so remove it from there.  Analysis of the code paths
  shows that nearly identical writes to these registers happen in later
  parts of the code.  The hanging problem on thinkpads when we change
  the interrupt routing type is something else.
