Spread-spectrum clock generation is supported by UB9702, but only
optionally required depending upon the hardware. Add a device-tree
property for enabling SSCG.

What does "optionally required" mean? Either it is required or it is
optional.

And the SSC values are not configurable?

I don't want three bindings for the same (see IMX8, STM32 and pull
