[PATCH v4 7/7] drm: nova: Expose a render node

[Alistair Popple <apopple@nvidia.com>]

nova-drm currently only exposes a primary node even though all of its
ioctls are already marked DRM_RENDER_ALLOW. Set the DRIVER_RENDER
feature so that a render node (/dev/dri/renderDXX) is created as well.

This is required to allow render and compute clients to interact with
nova-drm.
