The Tegra124 cpufreq driver works only with DFLL clock, which is a hardware-based frequency/voltage controller. The driver doesn't need to control the regulator itself. Hence remove that.
I think this is required for DFLL controlled I2C regulators because the regulator is queried for voltage selectors and I2C slave ID? Peter.
