Update the pciconf(8) database.

February 14, 2014 snapshot from http://pciids.sourceforge.net/
perfbias: Set to highest performance on detach path
acpica: Start task thread after all children of acpi are attached

So driver's post attach callback will run only after all devices of the
driver are properly attached.  Even when some devices' attach path is
blocked or moved to other CPU.
