Starting with v2024.10 dev_iommu_dma_unmap calls during device removal trigger a NULL pointer dereference since the the iommu device is removed before its user. The sparsely used DM_FLAG_VITAL flag is intended for this dependency. This series adds it to the Apple dart iommu driver and implements the two phased device removal to the EFI loader.
