 CONFIG_AARCH32_EL0 instead

Hi Andrew,

[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]

config: arm64-allnoconfig (attached as .config)
reproduce:
  wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
  chmod +x ~/bin/make.cross
  git checkout 4035143523cbf0106ee81f3ea585b363110c1ab6
  # save the attached .config to linux build tree
  make.cross ARCH=arm64
