Some recent tests with AIX guests showed that we don't tear down
MSIs that were allocated with the "change-msi" RTAS call, when
the guest is rebooted. This series teach PHBs to do the cleanup
at reset time.

This bug has always been there. Not sure it is worth the pain to
have this fixed in 4.1.

Since we've only recently started looking at AIX as a supported guest,
and these bugs don't appear to break Linux guests, no, I don't think
it is.
