powerpc/kexec_file: fix implicit decl error
kexec (PPC64) code calls memory_hotplug_max(). Add the header
declaration for it from <asm/mmzone.h>. Using <linux/mmzone.h> does not
work since the #include for <asm/mmzone.h> depends on CONFIG_NUMA=y,
which is not always set.
Fixes this build error/warning:
arch/powerpc/kexec/file_load_64.c: In function 'kexec_extra_fdt_size_ppc64':
arch/powerpc/kexec/file_load_64.c:993:33: error: implicit declaration of function 'memory_hotplug_max'
