[PATCH v2 04/12] drm/panfrost: Expose exception types to userspace

[Boris Brezillon <boris.brezillon@xxxxxxxxxxxxx>]

Job headers contain an exception type field which might be read and
converted to a human readable string by tracing tools. Let's expose
the exception type as an enum so we share the same definition.
