Subject: hid:StartLrAssignmentMode, hid:StopLrAssignmentMode,
 hid:SwapNpadAssignment

StartLrAssignmentMode and StopLrAssignmentMode don't require any implementation as it's just used for showing the screen of changing the controller orientation if the user wishes to do so.  Ever since #1634 this has not been needed as users can specify the controller orientation from the config and swap at any time. We store a private member just in case this gets used for anything extra in the future
