Stefano Stabellini f5079a9a2a xen/arm: introduce XENFEAT_direct_mapped and XENFEAT_not_direct_mapped ... Newer Xen versions expose two Xen feature flags to tell us if the domain is directly mapped or not. Only when a domain is directly mapped it makes sense to enable swiotlb-xen on ARM. Introduce a function on ARM to check the new Xen feature flags and also to deal with the legacy case. Call the function xen_swiotlb_detect.
