1ba6113a90a0 removed a lot of the kernel GPU channel, but method 0x128
was important as otherwise the GPU spams us with `CACHE_ERROR` messages.
We use the blit subchannel inside our vblank handling, so we should keep
at least this part.
v2: Only do it for NV11+ GPUs
Closes: https://gitlab.freedesktop.org/drm/nouveau/-/issues/201
Fixes: 4a16dd9d18 ("drm/nouveau/kms: switch to drm fbdev helpers")
