drm/nve0/gr: remove 0x404160 bashing from hub fuc

Triggers PIBUS interrupts due to register not existing anymore, and as a result HUB_SET_CHAN times out. After this commit, our fuc loads and can accelerate at least fbcon, X, glxgears and OA on NVE4. NVE7 not tested as of yet. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
