We could add a property "source-clock-divider = <2/3>" if it's needed!?

fsl,source-clock-divider

But, yes, this is a good solution (assuming that it is a board or SoC
characteristic, and not just a choice that the driver has the option
of making on it's own).

I was going to suggest the actual clock frequency of the I2C device.  It would
be value of gd->i2c1_clk or gd->i2c2_clk from U-Boot.  The actual divider value
is meaningless.
