[COMMON] i2c: exynos5: removed clk_unprepare during suspend

Fixed warning case during suspend.
There is the case that is calling clk_unprepare
even not called clk_disable during suspend_noirq.

flow of warning case:
exynos5_i2c_runtime_resume    (clk_enable)
-> exynos5_i2c_suspend_noirq  (clk_unprepare)
-> exynos5_i2c_runtime_suspend(clk_disable)
