xen: Delay invalidating extra memory
When the physical memory configuration is initialized the p2m entries for not pouplated memory pages are set to "invalid". As those pages are beyond the hypervisor built p2m list the p2m tree has to be extended. This patch delays processing the extra memory related p2m entries during the boot process until some more basic memory management functions are callable. This removes the need to create new p2m entries until virtual memory management is available.
