Suspend/Resume bug in PCI layer wrt quirks
Some quirks should be called with interrupt disabled, we can't directly call them in .resume_early. Also the patch introduces pci_fixup_resume_early and pci_fixup_suspend, which matches current device core callbacks (.suspend/.resume_early). TBD: Somebody knows why we need quirk resume should double check if a quirk should be called in resume or resume_early. I changed some per my understanding, but can't make sure I fixed all.
