The IOMMU probe deferral implementation requires a mechanism to detect if drivers for SMMU components are built-in in the kernel to detect whether IOMMU configuration for a given device should be deferred (ie SMMU drivers present but still not probed) or not (drivers not present). Add a simple function to IORT to detect if SMMU drivers for SMMU components managed by IORT are built-in in the kernel.
