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.
