With this
we get performace as the default governor.

could we use CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND as the default
instead? on Many TI SoCs using Highest frequency is not really too nice
of an idea for long periods of time. And not everything is upstream to
support things optimially - example avs class 0, 1.5 ABB consolidation
with cpufreq etc.. We definitely need thermal enabled as well for device
safety needs.

I propose the following instead:
