x86/mm: Introduce max_possible_pfn
max_possible_pfn will be used for tracking max possible PFN for memory that isn't present in E820 table and could be hotplugged later. By default max_possible_pfn is initialized with max_pfn, but later it could be updated with highest PFN of hotpluggable memory ranges declared in ACPI SRAT table if any present.
