Subject: [PATCH v2 2/5] dt-bindings: panel: add Feixin K101 IM2BA02 MIPI-DSI panel

Feixin K101 IM2BA02 is a 10.1" 800x1280 4-lane MIPI-DSI panel.

Add device tree binding for it.

Signed-off-by: Icenowy Zheng <icenowy@...c.io>

Changes in v2:
- Set backlight property to optional. (Technically this panel requires
  backlight, but theortically it can be not adjustable.)
- Tweaked the example to pass schema check.
