PCI: Report quirk timings with pci_info() instead of pr_debug()
With "initcall_debug", we report how long every PCI quirk took. Previously
we used pr_debug(), which means you have to figure out how to enable debug
output.
Log these timings using pci_info() instead so it doesn't depend on DEBUG,
CONFIG_DYNAMIC_DEBUG, etc.
Also, don't log anything at all unless "initcall_debug" is specified. This
matches what we do in do_one_initcall_debug().
