Hi, Dmitry

This is not the case, please see `opp-supported-hw = <0x2>;`.
Also: https://github.com/torvalds/linux/blob/master/drivers/cpufreq/qcom-cpufreq-nvmem.c#L334
This 1.5GHz Frequency only takes effect when the fuse value is `2'b1`.
I have tested this patch on both fused 1.2GHz and 1.5GHz devices.

Thanks,
Chukun
