x86: Make Dell Latitude E5420 use reboot=pci
commit b7798d28ec15d20fd34b70fa57eb13f0cf6d1ecd upstream.
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
660e34cebf0a11d54f2d5dd8838607452355f321 fixed this platform.
Unfortunately that turned out to be incorrect. ]
