    Input: allocate keycode for Display refresh rate toggle
    
    [ Upstream commit cfeb98b95fff25c442f78a6f616c627bc48a26b7 ]
    
    Newer Lenovo Yogas and Legions with 60Hz/90Hz displays send a wmi event
    when Fn + R is pressed. This is intended for use to switch between the
    two refresh rates.
    
    Allocate a new KEY_REFRESH_RATE_TOGGLE keycode for it.
