From: Bjorn Helgaas <bhelgaas at google.com>

This is a v6 of Puranjay's LTR _DSM support.  It should be functionally
equivalent, but I moved the bulk of the code from pci.c to aspm.c, since
it's only used for ASPM.  I also combined pci_ltr_encode() with the
existing encode_l12_threshold(), since they were doing essentially the same
thing.

I'll reply to the patches with a few more comments.
