From: Caleb Connolly <ca...@connolly.tech>
Add support for another variant of the rm69299 panel. This panel is
1080x2160 and is found in the shift-axolotl (SHIFT6mq).
Signed-off-by: Caleb Connolly <ca...@connolly.tech>
[narmstrong: removed cosmetic changes, fixed to apply, use enums to select mode]
