[Nouveau] NVIDIA display class method hardware documentation update

[Robert Morell]

Hi,

I'm pleased to announce that NVIDIA has released a new revision of the display
class method hardware documentation.  This release includes definitions for the
Pascal and Volta GPU architectures.

As always, you can find the files on download.nvidia.com:
