Subject: drm/lima: drop DRM_AUTH usage from the driver
Git-commit: 921d57323657eb5ae4a2ec460b137e62ee27c5c7
Patch-mainline: v5.4-rc1
References: bsc#1152472

The authentication can be circumvented, by design, by using the render
node.

From the driver POV there is no distinction between primary and render
nodes, thus we can drop the token.
