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.

Looks like there's a register for this at 0x60. That should be a 'reg' 
entry in the DT.

We discussed the usage of 'reg' here [1]. In short: This single
hw-register contains not only bits for the parallel output configuration
but also for the mipi-dsi configuration. So there should be no 'reg'
usage and instead let the syscon and driver do the correct handling.

Regards,
  Marco
