drm/amdgpu: Bump minor version for hot plug tests enabling.

This will allow to enable the tests only after latest fix
after which the tests passed on my system.

I tested on NV21 standalone and Vega 10 and Polaris as
pair with DRI_PRIME.

It's possible there might be still issues on ASICs i don't
have at my posession but that that the point of enbling
the tests finally - if other people during testing will
encounter errors they will report and I will be able to fix.

The releated merge request for enabling libdrm tests suite  is in
mesa/drm!227
