[PATCH v1 02/55] Documentation: media: camera-sensor: Mention v4l2_devm_sensor_clk_get() for obtaining the clock

[Mehdi Djait]

Add the new v4l2 helper devm_v4l2_sensor_clk_get() to Documentation. the
helper works on both DT- and ACPI-based platforms to retrieve a
reference to the clock producer from firmware.
