drm/etnaviv: add security handling mode enum
With the introduction of GPU security we have 3 different modes of GPU operation: - GPU core doesn't have security features -> no handling required - the security related states are handled by the kernel driver - the security related states are handled by a TrustZone application Add a enum to differentiate between the different operation modes.
