[PATCH rfcv1 6/6] 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. Currently only stage-2 translation is supported which is backed by shadow page table on host side. So we don't need exact matching of each bit of cap/ecap between vIOMMU and host. However, we can
