The recently introduced devm_v4l2_sensor_clk_get() helper aims at simplifying sensor drivers by centralizing clock handling code, as well as reducing cargo-cult and deprecated behaviour. A set of drivers implement external clock handling in a non-standard way. This can't be changed as there is a high risk of breaking existing platforms, but keeping the code as-is creates a risk of new drivers copying deprecated behaviour. To fix this, introduce a new devm_v4l2_sensor_clk_get_legacy() helper and use it in those driver. Compared to devm_v4l2_sensor_clk_get(), the new helper takes the "clock-frequency" property into account and sets the external clock rate on OF platforms, and adds the ability to specify a fixed default or fallback clock rate in case the "clock-frequency" property is not present.
