mm: make arch_has_descending_max_zone_pfns() static
clang produces a build failure on x86 for some randconfig builds after a change that moves around code to mm/mm_init.c: Cannot find symbol for section 2: .text. mm/mm_init.o: failed I have not been able to figure out why this happens, but the __weak annotation on arch_has_descending_max_zone_pfns() is the trigger here. Removing the weak function in favor of an open-coded Kconfig option check avoids the problem and becomes clearer as well as better to optimize by the compiler.
