[Isaku Yamahata]

Now updated msi implemenation by following the review.
Other patches were just adjusted.


Michael, thank you for merging portion of patch series.
That makes my life much easier.

> pcie port: define struct PCIEPort/PCIESlot and helper functions
> msix: clear not only INTA, but all INTx when MSI-X is enabled.
These 2 patches don't depend on MSI. Other patches do.

changes v1 -> v2:
- update msi
- dropped already pushed out patches.
- added msix patches.
