serial: of_serial: use devm_clk_get() instead of clk_get()

masahir0y · gregkh · commit 3a63d22425ff · 2015-06-01T06:55:12.000+09:00
The probe method of this driver calls clk_get(), but clk_put() is
missing from the remove callback.

Using the managed clk function is easier than fixing other parts.
