Subject: [PATCH v2 2/2] platform/x86: ideapad-laptop: map Fn + R key to KEY_REFRESH_RATE_TOGGLE

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.

The Fn + R key was incorrectly assigned to KEY_DISPLAYTOGGLE because it
is used to toggle the display on and off.

Map Fn + R key to the KEY_REFRESH_RATE_TOGGLE event code.

This commit depends on "platform/x86: ideapad-laptop: support Fn+R
dual-function key"
