Changes in v5:
- Add register helper function to cpufreq-dt for kernel users to use to
  establish a depmod dependency
- Drop patch that removes use of disable_cpufreq and re-add the patch to
  export said function
- Link to v4: https://lore.kernel.org/r/20250508-tegra124-cpufreq-v4-0-d142bcbd0234@gmail.com

Changes in v4:
- Move clock puts to remove instead of exit
- Link to v3: https://lore.kernel.org/r/20250421-tegra124-cpufreq-v3-0-95eaba968467@gmail.com

Changes in v3:
- In patch 1, set cpufreq_dt_pdev to an error after unregister on fail
  to prevent a potential double unregister on remove
- In patch 2, clean up clocks on exit
- Link to v2: https://lore.kernel.org/r/20250421-tegra124-cpufreq-v2-0-2f148cefa418@gmail.com

Changes in v2:
- Replace patch 1 with a patch to not use the unexported function
- Update patch 2 to add remove and exit routines
- Link to v1: https://lore.kernel.org/r/20250420-tegra124-cpufreq-v1-0-0a47fe126091@gmail.com
