These options only apply when not using DM_I2C. When using device trees, the dt will enable and control the speeds of the I2C controller(s) and these configuration options have no effect.
So disable them in DM_I2C mode. Otherwise they show up as decoys, and make it look like one is enabling I2C controllers and setting the speed when really it's doing nothing.
However, a system using a SPL build will not use DM_I2C in the SPL, even if DM_I2C is enabled for the main u-boot. And so the SPL might use the kconfig based I2C speed controls while the main u-boot does not.
