A recent patch introduced a new compiler warning because
two functions with non-void return type have no return
statement in omap-iommu.h for CONFIG_OMAP_IOMMU=n.
Fix this by adding return statements to these functions.
Fixes: d9c4d8a6cc ('iommu/omap: introduce new API for runtime suspend/resume control')
