[v5,1/6] dt-bindings: lcdif: Add i.MX93 LCDIF support

Commit Message

There is one LCDIF embedded in i.MX93 SoC to connect with
MIPI DSI controller through LCDIF cross line pattern(controlled
by mediamix blk-ctrl) or connect with LVDS display bridge(LDB)
directly or connect with a parallel display through parallel
display format(also controlled by mediamix blk-ctrl).  i.MX93
LCDIF IP is essentially the same to i.MX8MP LCDIF IP.  Add device
tree binding for i.MX93 LCDIF.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
