iommu: Add IOMMU uclass This uclass is intended to manage IOMMUs on systems where the IOMMUs are not in bypass mode by default. In that case U-Boot cannot ignore the IOMMUs if it wants to use devices that need to do DMA and sit behind such an IOMMU. This initial IOMMU uclass implementation does not implement and device ops and is intended for IOMMUs that have a bypass mode that does not require address translation. Support for IOMMUs that do require address translation is planned and device ops will be defined when support for such IOMMUs will be added.

iommu: Add Apple DART driver The DART is an IOMMU that is used on Apple's M1 SoC. This driver configures the DART such that it operates in bypass mode which is enough to support DMA for the USB3 ports integrated on the SoC.
