iommu: Split struct iommu_ops
Move the domain specific operations out of struct iommu_ops into a new structure that only has domain specific operations. This solves the problem of needing to know if the method vector for a given operation needs to be retrieved from the device or the domain. Logically the domain ops are the ones that make sense for external subsystems and endpoint drivers to use, while device ops, with the sole exception of domain_alloc, are IOMMU API internals.
