gpu: nvgpu: add a soft dependency on podgov module

Browse Source 
The present implementation of podgov driver doesn't
export any symbols and as a result, the dependency
between NVGPU driver and podgov is not established
by depmod. Fix that by adding a soft dependency.

MODULE_SOFTDEP("pre: governor_pod_scaling");

This allows loading the podgov governor before
nvgpu driver.
