This patch adds code to inject hwpoison into SGX memory. The SGX memory
is processor reserved memory that cannot be directly accessed by system
software.

Changes since v2:
- As suggested by Naoya Horiguchi <naoya.horiguchi@nec.com>, add a 
  new mf_action_page_type MF_MSG_SGX and use action_result() to
  show the page type and the action taken.
- Rewrite hwpoison.rst to show the output from dmesg after injection.
- Add reinette.chatre@intel.com to the email list. Sorry that I
  mistyped the email address in the previous emails.
- v2 Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org>

Changes since v1:
- Add a comment in hwpoison_inject as suggested by Miaohe
