Subject: arc: free_area_init(): take into account PAE40 mode
The arch_has_descending_max_zone_pfns() does not take into account physical
memory layout for PAE40 configuration.
With PAE40 enabled, the HIGHMEM is actually higher than NORMAL and
arch_has_descending_max_zone_pfns() should return false in this case.
