iommu: Make some functions static
The sparse tool complains as follows: drivers/iommu/iommu.c:386:5: warning: symbol 'iommu_insert_resv_region' was not declared. Should it be static? drivers/iommu/iommu.c:2182:5: warning: symbol '__iommu_map' was not declared. Should it be static? Those functions are not used outside of iommu.c, so mark them static.
