[PATCH v3 04/13] net: ethernet: ti: cpts: fix unbalanced clk api usage in cpts_register/unregister

There are two issues with TI CPTS code which are reproducible when TI CPSW ethX device passes few up/down iterations: - cpts refclk prepare counter continuously incremented after each up/down iteration; - devm_clk_get(dev, "cpts") is called many times. Hence, fix these issues by using
