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.
