x86: Make Dell Latitude E5420 use reboot=pci



Rebooting on the Dell E5420 often hangs with the keyboard or ACPI
methods, but is reliable via the PCI method.

[ hpa: this was deferred because we believed for a long time that the
  recent reshuffling of the boot priorities in commit
  660e34ce fixed this platform.
  Unfortunately that turned out to be incorrect. ]
