clk: move clk_disable_unused after clk_core_disable_unprepare function

No function level change, just moving code place.
clk_disable_unused function will need to call clk_core_prepare_enable/
clk_core_disable_unprepare when adding CLK_OPS_PARENT_ENABLE features.
So move it after clk_core_disable_unprepare to avoid adding forward
declared functions later.
