[Nouveau] NVS 4200M support

[Dmitry A. Ashkadov]

Hello!

I have Nvidia NVS 4200M installed on my laptop. Does nouveau support it?
If I change video to Discrete card in BIOS, then nouveau (version 
0.0.16) logs:
> nouveau: probe of 0000:01:00.0 failed with error -22
and
> [drm] failed to open device
> No devices detected

Thank you!
