The latest version of the Mali C55 driver has changed the format
accepted by the ISP sink pad to be the 20-bit wide.
The CSI-2 receiver handles the format expansion internally by
propagating the sensor produced format from its sink to the 20-bit
expanded version on its source pad.
Instead of re-applying the sensor format to the CSI-2 receiver source
pad (which is now an invalid operation) read from there the format
propagated by the driver internally and further propagate it to the ISP
subdevice.
