nouveau GSP fixes
This is a collection of nouveau debug prints, memory leak, a very
annoying race condition causing system hangs with prime scenarios,
and a fix from Lyude to get the panel on my laptop working.
I'd like to get these into 6.7,
Dave.

[PATCH v3 00/15] NVKM GSP RPC kernel docs, cleanups and fixes
Hi folks:
Here is the leftover of the previous spin of NVKM GSP RPC fixes, which
is handling the return of large GSP message. PATCH 1 and 2 in the previous
spin were merged [1], and this spin is based on top of PATCH 1 and PATCH 2
in the previous spin.
Besides the support of the large GSP message, kernel doc and many cleanups
are introduced according to the comments in the previous spin [2].
