Extend __mtk_clk_simple_probe() to run devm_of_platform_populate() when the new 'populate_children' flag is set, reducing boilerplate. Note that explicit of_platform_depopulate() calls in remove functions are unnecessary because devm_of_platform_populate() is managed by devres and cleans up automatically.
