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.
