The GPU architecture to be exposed to user-space. This adds a public enum to the userspace headers for each chip architecture. Nova-core can then use this enum to define its architectures. This does create a coupling between nova-drm and nova-core whereby nova-core depends on the values defined by the user-space API for nova-drm. However this is entirely appropriate as nova-core must be bound by the UAPI headers as the enum values are read by nova-core and passed through to user-space. It also requires a minor change to the bounded_enum! macro to match the architecture values in an expression context.
