cpufreq as such will work as expected and will scale MPU and L3
frequency based on system load. However if any driver is not
requesting for the required l3 frequency, then we might start seeing
issues at driver level (like FIFO underflow etc due to l3 running at
lower rate).

So my suggestion is not to keep ondemand as the default governor and
if someone wants to experiment, they can enable it.
