security: tlk_driver: stage new interface structs
The current structs passed between the client lib and kernel aren't sized to allow 64bit pointers to work. This code stages ioctls based on structs that can handle 32bit or 64bit references. Once the supporting TLK library and kernel changes are checked in, we'll flip over to using these code paths.
