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.

                      Specify the physical parallel bus width.

                      This property is optional if the display bus-width
                      matches the SoC bus-width, e.g. a 18-bit RGB666 (display)
                      is connected and all 18-bit data lines are muxed to the
                      parallel-output pads.

                      This property must be set to 18 to cut only the LSBs
                      instead of the MSBs in case a 24-bit RGB888 display is
                      connected and only the lower 18-bit data lanes are muxed
                      to the parallel-output pads.
