[2/2] platform/x86: ideapad-laptop: map Fn + R key to KEY_FN_R

Commit Message

Newer Lenovo Yogas (e.g. Yoga 7 14ARB7) and Legions with 60Hz/90Hz
displays send a wmi event when Fn + R is pressed. This is intended for
use to adjust refresh rate, but there is no silkscreen print on the R
key to indicate this.

The Fn + R key is incorrectly assigned to KEY_DISPLAYTOGGLE, as the
latter is used to toggle the display on and off.

Map the Fn + R key to a more generic KEY_FN_R event code, since the
refresh rate toggle feature is not common and is only used by a few
Lenovo laptops.

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