Note that we can now use the CONFIG_GENERIC_CPUFREQ_CPU0, so let's only enable that.

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:
