iommu/mediatek: Mark PM functions as __maybe_unused
When CONFIG_PM is unset, we get a harmless warning for this driver:
drivers/iommu/mtk_iommu.c:665:12: error: 'mtk_iommu_suspend' defined but not used [-Werror=unused-function]
drivers/iommu/mtk_iommu.c:680:12: error: 'mtk_iommu_resume' defined but not used [-Werror=unused-function]
Marking the functions as __maybe_unused gits rid of the two functions
and lets the compiler silently drop the object code, while still
doing syntax checking on them for build-time verification.
