[PATCH v3 1/3] dt-bindings: lcdif: Document a imx6sx-lcdif fallback

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

imx6sx.dtsi has the following lcdif entries:

compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";

This causes the following dt-schema warning:

['fsl,imx6sx-lcdif', 'fsl,imx28-lcdif'] is too long

To keep DT compatibility, document 'fsl,imx28-lcdif' as a possible
'fsl,imx6sx-lcdif' fallback.

Signed-off-by: Fabio Estevam <festevam at denx.de>

Changes since v2:
- Only document fsl,imx6sx-lcdif with a fallback.
