Previously, the 1GHz variants were marked as a turbo,
because that variant has reduced thermal operating range.

Now that the thermal throttling is in place, it should be
safe to remove the turbo-mode from the 1GHz variants, because
the CPU will automatically slow if the thermal limit is reached.

Thanks applying into omap-for-v5.12/dt.
