Subject: iommu: Define dev_iommu_fwspec_get() for !CONFIG_IOMMU_API
Git-commit: 0008d0c3b1ab03b046b04b7bd9d70df1e2fffbfc
Patch-mainline: v5.7-rc1
References: bsc#1175713

There are users outside of the IOMMU code that need to call that
function. Define it for !CONFIG_IOMMU_API too so that compilation does
not break.
