mm/memblock: add physical memory list
Add the physmem list to the memblock structure. This list only exists if HAVE_MEMBLOCK_PHYS_MAP is selected and contains the unmodified list of physically available memory. It differs from the memblock memory list as it always contains all memory ranges even if the memory has been restricted, e.g. by use of the mem= kernel parameter.
