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.
