PCI: Document that most pci options are shared between i386 and x86-64
Since the code is shared pretty much most of the pci= options are shared, but kernel-parameters.txt marked most of them as i386 only. Signed-off-by: Andi Kleen <firstname.lastname@example.org> Signed-off-by: Jesse Barnes <email@example.com>
