Currently, users are allowed to map static shared memory in a non-direct-mapped way for direct-mapped domains. This can lead to clashing of guest memory spaces. Also, the current extended region finding logic only removes the host physical addresses of the static shared memory areas for direct-mapped domains, which may be inconsistent with the guest memory map if users map the static shared memory in a non-direct-mapped way. This will lead to incorrect extended region calculation results. To make things easier, add restriction that static shared memory should also be direct-mapped for direct-mapped domains. Check the host physical address to be matched with guest physical address when parsing the device tree. Document this restriction in the doc.
