PCI changes for v3.17

Hi Linus,

These are for the v3.17 merge window, not for v3.16.

I'll be on vacation until Aug 11, and I suspect the merge window will open before then, so I'm sending this to you early. There are more things I'd like to get into v3.17, so I hope to send another pull request soon after I return.

The most notable pieces here are:

- Support BARs up to 128GB (up from 8GB)
- Fix SR-IOV resource assignment when we fail to expand a resource
- Rework pciehp to handle a common hardware erratum
- Cleanup MSI
- Fix NIC renaming issue
- Fix VGA default device issue on EFI systems
- Fix ASPM configuration (previously we didn't enable it as expected)

Alex Williamson has graciously agreed to take care of any major issues with this if you take it before I return.

The following changes since commit 7171511eaec5bf23fb06078f59784a3a0626b38f:
