AMD IOMMU emulation patches v3

Hi,

Please have a look at these and merge if you wish. I hope I've addressed the issues people have raised.

Some changes from the previous RFC:
- included and updated the other two device patches
- moved map registration and invalidation management into PCI code
- AMD IOMMU emulation is always enabled (no more configure options)
- cleaned up code, I now use typedefs as suggested
- event logging cleanups

BTW, the change to pci_regs.h is properly aligned but the original file contains tabs.

Cheers,
Eduard
