t23x: overlay: Disable throttling for safety IGX

Browse Source 
The clock frequency should be static and avoid any kind of throttling
mechanism for safety IGX. So, this change overwrites the cooling states
of the cpufreq and the devfreq cooling devices to 0 to avoid entering
any other cooling states that could throttle the clocks.
