drm/nv50: use "nv86" tlb flush method on everything except 0x50/0xac
It has been reported that this greatly improves (and possibly fixes completely) the stability of NVA3+ chipsets. In traces of my NVA8, NVIDIA now appear to be doing this too. The most recent traces of 0x50 and 0xac I could find don't show NVIDIA checking PGRAPH status on these flushes, so for now, we won't either. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
