Revert "ACPI / hotplug / PCI: Runtime resume bridge before rescan"
This reverts commit 16468c783cb4cf72475dcda23fabecb4a4bb0e17. Bisection showed that it was the root cause for a resume hang on a bog-standard all-Intel laptop (Sony Vaio Pro 11), and reverting fixes the hang. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
