[POWERPC] Fix MAX_ORDER config problem

The allyesconfig (among others) build was giving this:

                 from include/linux/slab.h:14,

arch/powerpc/kernel/asm-offsets.c:17:
include/linux/mmzone.h:791:2: error: #error Allocator MAX_ORDER exceeds SECTION_SIZE

Kconfig options are order depenendent, so move the setting of
FORCE_MAX_ZONEORDER to after the setting of PPC_64K_PAGES. Also add an
explicit !PPC_64K_PAGES.
