When creating a hardware domain, have the dom0less code call construct_hwdom() which is shared with the dom0 code. The hardware domain requires building that best matches the dom0 build path. Re-use it to keep them in sync. The device tree node of the dom0less config is now passed into construct_hwdom(). dom0 uses /chosen for process_shm while a hwdom will use the value from its dom0less device tree node.
