Re-spin of RFC patch from ~2.5 years ago [1]. v4l2 controls for privacy LEDs has landed, but the DT part was left out. Introduce missing dt-bindings, and commonize 'leds' parameter. Finally, add a patch to enable privacy-led on Lenovo Thinkpad x13s.
With recent inflow of arm64-power laptops (Snapdragon X1E/X1P) which mostly use MIPI cameras, this feature becomes more desired. Original rebased patch is still working as expected (with respective DT changes) on Dell XPS 9345.
