Subject: [PATCH v2 0/2] ARM: at91: add support for secure suspend on sama5d2

Now that OP-TEE support for sama5d2 is more complete, add support to
execute SMC calls and to set suspend mode. This series adds new files
to be able to execute SMC calls targeting OP-TEE secure monitor and
secure suspend support uses it.

Changes V2:
 - Add suspend mode SMC in already existing secure support
