    x86/shutdown: use ACPI reboot method for Dell PowerEdge R540
    
    When EFI booting the Dell PowerEdge R540 it consistently wanders into
    the weeds and gets an invalid opcode in the EFI ResetSystem call. This
    is the same bug which affects the PowerEdge R740 so fix it in the same
    way: quirk this hardware to use the ACPI reboot method instead.
