Subject: drm/msm: drop DRM_AUTH usage from the driver
Git-commit: 88209d2c5035737f96bcfc2fd73c0fd8d80e9bf1
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.
