If a PCI mode reboot is performed on the ASRock Z170 Extreme4, a power

This will only take effect if PCI mode is manually used. It'll be too late
in the reboot process to prepare for power off if the other reboot methods
fail.

It is necessary to re-order the processing of DMI checks because this quirk
must apply even if a reboot= command line parameter is used as that's the
only way to specify a PCI mode reboot.
