This project is something I'd like to get done, but it requires a
little more work.  If it were this simple, I would have done it long
ago :)

For one thing, we need to update all the Kconfig files that already
include drivers/pci/pcie/Kconfig at the same time.  On x86,
arch/x86/Kconfig already includes both:

  source "drivers/pci/pcie/Kconfig"
  source "drivers/pci/Kconfig"

With your patch applied, I see these new warnings:

  05:42:09 ~/linux (wip/bogicevic-kconfig)$ make menuconfig
  ...
  scripts/kconfig/mconf  Kconfig
  drivers/pci/pcie/Kconfig:61:warning: choice value used outside its choice group
  drivers/pci/pcie/Kconfig:67:warning: choice value used outside its choice group
  drivers/pci/pcie/Kconfig:74:warning: choice value used outside its choice group

I see that you did verify that removing the source line from
arch/x86/Kconfig does the right thing.  We need to put all the related
changes in a single patch so it is self-contained.  The tree should be
buildable and functional at every stage.
