[PATCH v6 8/9] arm64: dts: imx943-evk: Add display support using IT6263

[Laurentiu Palcu <laurentiu.palcu@oss.nxp.com>]

The ITE IT6263 based NXP LVDS to HDMI converter can be attached to the
i.MX943 EVK board LVDS port using the mini-SAS connector. Since this is
the default configuration for the EVK, add support for it here.
