[PATCH] drm/nouveau/core: recognise GP107 chipset

[Daniel Drake]

From: Chris Chiu <chiu at endlessm.com>

This new graphics card was failing to initialize with nouveau due to
an "unknown chipset" error.

Copy the GP106 configuration and rename for GP107/NV137. We don't
know for certain that this is fully correct, but brief desktop testing
suggests this is working fine.
