iommu/omap: Mark pm functions __maybe_unused
The runtime_pm functions are unused when CONFIG_PM is disabled:
drivers/iommu/omap-iommu.c:1022:12: error: unused function 'omap_iommu_runtime_suspend' [-Werror,-Wunused-function]
static int omap_iommu_runtime_suspend(struct device *dev)
drivers/iommu/omap-iommu.c:1064:12: error: unused function 'omap_iommu_runtime_resume' [-Werror,-Wunused-function]
static int omap_iommu_runtime_resume(struct device *dev)
Mark them as __maybe_unused to let gcc silently drop them
instead of warning.
Fixes: db8918f61d51 ("iommu/omap: streamline enable/disable through runtime pm callbacks")
