    x86: don't apply reboot quirks if reboot set by user
    
    If reboot= is specified on the command-line, don't apply reboot quirks
    to allow the command-line option to take precedence.
    
    This is a port of Linux commit 5955633e91bf ("x86/reboot: Skip DMI
    checks if reboot set by user").
    
    Signed-off-by: Ross Lagerwall <ross.lagerwall@xxxxxxxxxx>
    
    Leverage (and make apply on top of) c643fb110a ("x86/EFI: allow
    reboot= overrides when running under EFI").
