[PATCH 1/3] drm/mxsfb: Add an entry for "fsl,imx8mq-lcdif"

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@denx.de>

On i.MX6SX, the LCDIF has an associated power domain.

However, i.MX8MQ does not have an LCDIF power domain.

imx8mq.dtsi has the following compatible string:

compatible = "fsl,imx8mq-lcdif", "fsl,imx6sx-lcdif";

which causes the following dt-schema warning:

imx8mq-evk.dtb: lcd-controller@30320000: 'power-domains' is a required property
	from schema $id: http://devicetree.org/schemas/display/fsl,lcdif.yaml#

To prevent this problem, add a specific fsl,imx8mq-lcdif entry in
the driver to properly handle such a power-domain requirement difference.
