[PATCH v2] Documentation: nouveau: Update GSP message queue kernel-doc reference

[Bagas Sanjaya <bagasdotme@gmail.com>]

GSP message queue docs has been moved following RPC handling split in
8a8b1ec5261f20 ("drm/nouveau/gsp: split rpc handling out on its own"),
before GSP-RM implementation is versioned in c472d828348caf
("drm/nouveau/gsp: move subdev/engine impls to subdev/gsp/rm/r535/").
However, the kernel-doc reference in nouveau docs is left behind, which
triggers htmldocs warnings:

ERROR: Cannot find file ./drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c
WARNING: No kernel-doc for file ./drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c

Update the reference.

Fixes: c472d828348c ("drm/nouveau/gsp: move subdev/engine impls to subdev/gsp/rm/r535/")
Fixes: 8a8b1ec5261f ("drm/nouveau/gsp: split rpc handling out on its own")
