[PATCH v2] drm/nouveau: don't detect DSM for non-NVIDIA device
...ode if this is an NVIDIA card, and just
return if it isn't.
This, together with commit d22915d22ded ("drm/nouveau/devinit/tu102-:
wait for GFW_BOOT_PROGRESS == COMPLETED") developed independently and
landed earlier, fixes runtime power management of the NVIDIA card in
Lenovo Legion 5-15ARH05. Without this patch, the GPU resumption code
will "timeout", sometimes hanging userspace.
As a bonus, we'll also stop preventing _PR3 usage from the bridge for
unrelated devices, which is always nice, I guess.
