I'd like to include Layerscape in the LTSSM_STATE_MASK cleanup done by Fabio: https://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/commit/?h=pci/host-designware&id=4788fe6ebf4594c9a95b620cbff05147c8504823 I don't have specs for any of these devices, so I don't know if this is really something that can vary between the different DesignWare-based devices, or if they all should use a mask of 0x1f.
