[PATCH] clk: samsung: exynos5433: mark PM functions as __maybe_unused

[Arnd Bergmann <arnd@arndb.de>]

The suspend/resume functions are referenced conditionally, causing
a harmless warning when CONFIG_PM is disabled:

drivers/clk/samsung/clk-exynos5433.c:5476:12: error: 'exynos5433_cmu_resume' defined but not used [-Werror=unused-function]
drivers/clk/samsung/clk-exynos5433.c:5453:12: error: 'exynos5433_cmu_suspend' defined but not used [-Werror=unused-function]

This marks both as __maybe_unused to shut up the warning.

Fixes: 523d3de41f02 ("clk: samsung: exynos5433: Add support for runtime PM")
