The main problem I see with this proposal is that clk_register_flexgen() 
is called for several SoCs (STiH407/410/418...).
Each of these SoCs have this clock, but maybe STiH407 will need the 
flag, but not STiH410 and STiH418.
So I think the best place to set this information is in DT, where the 
differentiation is made between the SoCs.

Kind regards,
Maxime
