I just noticed a nit here: we should probably align with other
parts of this file by using "HWPT" v.s. "domain"? I.e.

+ * @IOMMU_HWPT_ALLOC_NEST_PARENT: If set, allocate a HWPT which can serve
+ *                                as the parent HWPT in the nesting
+ *                                configuration.

Thanks
Nic
