net: ethernet: ti: cpts: use devm_get_clk_from_child
Use devm_get_clk_from_child() instead of devm_clk_get() and this way allow to group CPTS DT properties in sub-node for better code readability and maintenance. Roll-back to devm_clk_get() if devm_get_clk_from_child() fails for backward compatibility.
