The datasheets for the SoCs have small nuances around the Pre-Clip registers ELPrC and EPPrC in three use-cases, interlaced images, embedded data and RAW8 input. On V4H the values written to the registers are based on odd numbers while on V4M they are even numbers, values are based on the input image size. No board that uses these SoCs which also have the external peripherals to test these nuances exists. Most likely this is an issue in the datasheet. Before adding bindings for V4M add a family compatible fallback for Gen4. That way the driver only needs to be updated once for Gen4, and we still have the option to fix any problems in the driver if any testable differences between the SoCs are found. There are already DTS files using the V3U and V4H compatibles which needs to be updated to not produce a warning for DTS checks. The driver also needs to kept the compatible values to be backward compatible , but for new Gen4 SoCs such as V4M we can avoid this.

Add this fallback to the V3U DTSI. There is no functional change, but the addition of the family fallback in the bindings produces warnings for V3U for DTS checks if they are not added.
