From: Joao Martins <joao.m.mart...@oracle.com> Store the value of @caps returned by iommufd_backend_get_device_info() in a new field HostIOMMUDeviceCaps::hw_caps. Right now the only value is whether device IOMMU supports dirty tracking (IOMMU_HW_CAP_DIRTY_TRACKING).
This is in preparation for HostIOMMUDevice::realize() being called early during attach_device().
