Rasmus Villemoes 8e2614bbf6 PCI: Add include guard to include/linux/pci_ids.h ...

Adding an include guard frees the preprocessor from reparsing over 2600
#defines in the cases where pci_ids.h is somehow included more than once.
This gives a tiny-but-measurable performance improvement when compiling
such files.
