Protected Methods
zx_status_t Create (fbl::RefPtr<BusTransactionInitiatorDispatcher> bti, PinnedVmObject pinned_vmo, uint32_t perms, KernelHandle<PinnedMemoryTokenDispatcher> * handle, zx_rights_t * rights)Set the permissions of |pinned_vmo|'s pinned range to |perms| on
behalf of |bti|. |perms| should be flags suitable for the Iommu::Map()
interface. Must be created under the BTI dispatcher's lock.
