[PATCH] powerpc: Fix build of 64 bit little endian with CONFIG_KEXEC=n

On ppc64le, builds with CONFIG_KEXEC=n fail with:

arch/powerpc/platforms/pseries/setup.c: In function ‘pseries_big_endian_exceptions’:
arch/powerpc/platforms/pseries/setup.c:403:13: error: implicit
declaration of function ‘kdump_in_progress’ [-Werror=implicit-function-declaration]
  if (rc && !kdump_in_progress())

This is because pseries/setup.c includes <linux/kexec.h>, but
kdump_in_progress is defined in <asm/kexec.h>. This is a problem because
the former only includes the latter if CONFIG_KEXEC_CORE=y.

Fix by including <asm/kexec.h> directly, as is done in powernv/setup.c.

Applied to powerpc fixes, thanks.
