nvidia: module license 'NVIDIA' taints kernel

[Juno Computers]

The nvidia module is not loaded properly on kernel 5.8 which is causing the fan/thermals to go crazy. This only happens when running on Nvidia and Ondemand. No issues on Intel graphics.

The error goes away on kernel 5.4

@Peter, please file a new bug instead as this one is about thermal control and has expired.
