Subject: [PATCH v3 1/2] dt-bindings: soc: imx93-media-blk-ctrl: Add PDFC subnode to schema and example

i.MX93 SoC mediamix blk-ctrl contains one DISPLAY_MUX register which
configures parallel display format by using the "PARALLEL_DISP_FORMAT"
field. Document the Parallel Display Format Configuration(PDFC) subnode
and add the subnode to example.
