drm: nova: Add GPU architecture enum to nova-drm UAPI
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.
