From: Fabio Estevam <festevam@xxxxxxx>
mx6sl.dtsi and imx6sll.dtsi have the following lcdif entries:
compatible = "fsl,imx6sl-lcdif", "fsl,imx28-lcdif";
This causes dt-schema warnings as the current binding only
allow 'fsl,imx6sx-lcdif' as fallback.
['fsl,imx6sl-lcdif', 'fsl,imx28-lcdif'] is too long
['fsl,imx6sll-lcdif', 'fsl,imx28-lcdif'] is too long
The imx6sx-lcdif programming model has more advanced features, such
as overlay plane and the CRC32 support than the imx28-lcdif IP.
Expand the imx6sl/imx6sll lcdif fallbacks to accept a less specific
fsl,imx28-lcdif fallback:
compatible = "fsl,imx6sl-lcdif", "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";
This helps keeping DT compatibility as well as using the more advanced
lcdif features found on imx6sl and imx6sll.

Changes since v2:
- Make the three compatible entres the only valid combination
for imx6sl and imx6sll (Andreas).
