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.
