This patch defines a new bit reported in the hw_cap field of struct xen_sysctl_physinfo to indicate whether the platform supports sharing of HAP page tables (i.e. the P2M) with the IOMMU. This informs the toolstack whether the domain needs extra memory to store discrete IOMMU page tables or not.NOTE: This patch makes sure iommu_hap_pt_shared is clear if HAP is not supported or the IOMMU is disabled, and defines it to false if !CONFIG_HVM.
