chipid_mem is initialized with memory_region_init_ram_ptr() function with chipid_and_omr
array as buffer argument. During initialization memory region size is aligned to page size,
but size of static array chipid_and_omr is less then TARGET_PAGE_SIZE. This could result
in errors in some cases, specifically, it could cause segfault during VM saving.
Setting chipid_and_omr aray size to TARGET_PAGE_SIZE helps us to avoid any problems.
