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.

v3->v4:
* No change.

v2->v3:
* Newly introduced to replace the standalone dt-binding in v1 and v2. (Rob)
* Resend with Conor's R-b tag and with the patch rebased upon v6.11-rc1.
