Replace ifdef with __maybe_unused to silence compiler warning on when
SUSPEND=n and PM=y:
drivers/char/hw_random/exynos-rng.c:166:12: warning: ‘exynos_rng_suspend’ defined but not used [-Wunused-function]
static int exynos_rng_suspend(struct device *dev)
^
drivers/char/hw_random/exynos-rng.c:171:12: warning: ‘exynos_rng_resume’ defined but not used [-Wunused-function]
static int exynos_rng_resume(struct device *dev)
