Merge: cpufreq: Enable CPUFREQ thermal cooling for NVIDIA Orin

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/2035

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2165104

Enable CPUFREQ cooling

Register Tegra194 CPUFREQ driver as a cooling device by populating CPUFREQ_IS_COOLING_DEV flag.
This change enables CPU frequency throttling upon passive trip points being crossed.

This patch is necessary to support cpufreq thermal cooling on the NVIDIA Orin
