Subject: powerpc/8xx: Fix build with hugetlbfs enabled

8xx uses the slice code when hugetlbfs is enabled. We missed a header
include on 8xx which resulted in the below build failure:

  config: mpc885_ads_defconfig + CONFIG_HUGETLBFS

  arch/powerpc/mm/slice.c: In function 'slice_get_unmapped_area':
  arch/powerpc/mm/slice.c:655:2: error: implicit declaration of function 'need_extra_context'
  arch/powerpc/mm/slice.c:656:3: error: implicit declaration of function 'alloc_extended_context'

on PPC64 the mmu_context.h was included via linux/pkeys.h
