The use of SIMPLE_DEV_PM_OPS() means that the suspend/resume
functions are now unused when CONFIG_PM is disabled:

drivers/clk/samsung/clk-exynos-clkout.c:219:12: error: 'exynos_clkout_resume' defined but not used [-Werror=unused-function]
  219 | static int exynos_clkout_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~
drivers/clk/samsung/clk-exynos-clkout.c:210:12: error: 'exynos_clkout_suspend' defined but not used [-Werror=unused-function]
  210 | static int exynos_clkout_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~~

Mark them as __maybe_unused to shut up the otherwise harmless warning.

Fixes: 9484f2cb8332 ("clk: samsung: exynos-clkout: convert to module driver")
