[PATCH 3/4] rtc: s3c: use unified functions for enable/disable of clk

[Joonyoung Shim]

The driver uses clk_prepare_enable()/clk_disable_unprepare() only in
probe only, elsewhere, use the unified functions for enable/disable of
clk, e.g. s3c_rtc_enable_clk() / s3c_rtc_disable_clk(), so it's better
to use them for consistency of code.
