[PATCH rfcv2 14/18] intel_iommu: Add a framework to check and sync host IOMMU cap/ecap

From: Yi Liu Add a framework to check and synchronize host IOMMU cap/ecap with vIOMMU cap/ecap. The sequence will be: vtd_cap_init() initializes iommu->cap/ecap. vtd_check_hdev() update iommu->cap/ecap based on host cap/ecap. iommu->cap_frozen set when machine create done, iommu->cap/ecap becom
