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

[Ilia Mirkin]

I believe what's missing at this point is a mmiotrace of the NVIDIA
driver to make sure that there's nothing different about this GPU. If
you can make one (see https://wiki.ubuntu.com/X/MMIOTracing for a
guide - should end up ~100MB uncompressed), please send a compressed
one to mmio.dumps at gmail.com or make available some other way.
