i2c: exynos5: add CONFIG_PM_SLEEP to suspend/resume functions

Browse Source 
Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.

  warning: 'exynos5_i2c_suspend_noirq' defined but not used [-Wunused-function]
  warning: 'exynos5_i2c_resume_noirq' defined but not used [-Wunused-function]
