Some IPQ6000 SoCs (fused)[1] have CPU frequencies up to 1.2GHz,
so add this frequency.

[1] Usually the SBL version is BOOT.XF.0.3-00086-IPQ60xxLZB-1

opp-supported-hw is selected for all IPQ6000. Please add more details
here. Is 1.2 GHz really to be enabled for all IPQ6000?

The 1.2GHz frequency is available only if the fuse is IPQ6000.
I will try to add more details.

Thanks,

You can respond here and post new iteration once we settle on something.
