Subject: [PATCH] powerpc/powernv: Fix build error when CONFIG_SMP=n

Fix the following build error when compiled with CONFIG_SMP=n
arch/powerpc/platforms/powernv/setup.c: In function ‘pnv_kexec_wait_secondaries_down’:
arch/powerpc/platforms/powernv/setup.c:179:4: error: implicit declaration of function ‘get_hard_smp_processor_id’ [-Werror=implicit-function-declaration]
    rc = opal_query_cpu_status(get_hard_smp_processor_id(i),

The usage of get_hard_smp_processor_id() needs the declaration from <asm/smp.h>.
The file setup.c includes <linux/sched.h>, which in-turn includes <linux/smp.h>.
However, <linux/smp.h> includes <asm/smp.h> only on SMP configs and hence UP
builds fail. Fix this by directly including <asm/smp.h> in setup.c
unconditionally.
