Add the flag to the relevant clocks in the C code, e.g. in
clk_register_flexgen():

        if (!strcmp(name, "clk-icn-cpu"))
                init.flags |= CLK_ENABLE_HAND_OFF;

You can imagine doing "flex_flags |= CLK_ENABLE_HAND_OFF" in
st_of_flexgen_setup(), depending on the presence of such a property.

However, not disabling clocks is a software policy, not a hardware description,
so IMHO it doesn't belong in DT.
