Dear Lorenzo,

since we have dropped some patches from the second batch, I thought that
we could instead replace them with another 7 small changes, that we can
hopefully get applied in this cycle.

Description:
- patch 1 just adds a small explanation to pci-bridge-emul, no functional
  change
- patches 2 and 3 add support for some more registers on emulated bridge
- patch 4 is taken from the MSI patches we dropped from batch 2, but since
  it only clears MSIs and adds a useful macro, and makes no changes that
  depend on the API change request by Marc, I think we can add it now
  (especially since patch 5 uses this new macro)
- patches 5-7 make driver unbind work better
