Subject: drm/etnaviv: drop DRM_AUTH usage from the driver
Git-commit: b8602f9a65a6744060cde6fb153729e6a4099437
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.
