This is a minor update of a patch I posted earlier [1] when Paul reported an unreasonably long time spent in PCI quirks during boot [2]. This doesn't fix the slow quirks, but might help find them.
We previously printed the time taken by each quirk if "initcall_debug" was specified. With these patches, we'll print it even without "initcall_debug" if the quirk takes longer than 10ms.
I did notice one quirk (quirk_apple_poweroff_thunderbolt()) in the suspend path that sleeps for 300ms, so this will probably make suspend noisier on Apple systems.
