[PATCH v5 3/4] media: s5p-tv: Fix sdo driver to work with CCF

[Mateusz Krawczuk]

Replace clk_enable by clock_enable_prepare and clk_disable with clk_disable_unprepare.
Clock prepare is required by Clock Common Framework, and old clock driver didn`t support it.
Without it Common Clock Framework prints a warning.
