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.
