Subject: arm64: dts: colibri-imx8x: fix dsi to hdmi adapter configuration

Add hdmi_connector and all relevant configurations.
Move pinctrl, ddc-i2c-bus and hdp-gpio from lt8912_hdmi
to hdmi_connector.
Correct lt8912_hdmi compatible and fix its ports configuration.

Upstream-Status: Pending

No support in upstream linux
