x86: respect memory size limiting via mem= parameter When limiting memory size via kernel parameter "mem=" this should be respected even in case of memory made accessible via a PCI card. Today this kind of memory won't be made usable in initial memory setup as the memory won't be visible in E820 map, but it might be added when adding PCI devices due to corresponding ACPI table entries. Not respecting "mem=" can be corrected by adding a global max_mem_size variable set by parse_memopt() which will result in rejecting adding memory areas resulting in a memory size above the allowed limit.
