Use the standard #defines rather than creating local definitions for
PCIe Capability ASPM fields.

I'll pick up the iwlwifi ones if you want, or do you want to merge them
somewhere centrally instead?

They do depend on a previous patch that adds the #defines to
include/uapi/linux/pci_regs.h
(http://marc.info/?l=linux-pci&m=135474107109010&w=2).

I think I'll merge at least the PCI core parts of this via my PCI tree
in the v3.8 merge window next week. If it won't cause conflicts for
you, I could include the iwlwifi bits there, too. If it does, at
least the #define will exist and you can merge it at your leisure.

Ok, that's fine, feel free to include the iwlwifi bits.
