Add a flag to the command submission IOCTL structure which when present indicates that this command submission should be treated as secure. The kernel driver uses this flag to determine whether the engine should be transitioned to secure or unsecure, or the work can be submitted to a secure queue depending on the IP.
v3: the flag is now at command submission IOCTL
