  1. plat-ti: Add Suspend/Resume support for AM43xx

    When the non-secure world is attempting to suspend it will call into the
    secure side using a platform service call. We implement this here in
    OP-TEE by saving the needed secure side registers.
    
    On resume the ROM will restore the secure side to its original
    configuration and OP-TEE will be re-entered from its boot reset vector.
    Add a check for the resume case and restore the secure registers if we
    are resuming.
