Subject: [PATCH v2 0/2] arm64: dts: imx8mq: Add eLCDIF controller

With some minimal support on imx8mq we might as well add it to the DT

Changes from v1:
- Per review comments by Fabio Estevam
- Document compatible
- use lcd-controller instead of lcdif as node name
- Add Reviewed-by: from Fabio Estevam, thanks!
