[kernel][iommu] New Map/Unmap IOMMU API

Changes the Map/Unmap design of the Iommu interface to use an opaque
mapping token, instead of operating directly on device address ranges.
This allows for separating the mapping of a range, with querying the
device contiguous portions of it. The existing IOMMU implementations
are able to support this change without actually needing to allocate or
store any additional metadata.
