(This is a v3 of patch "drm/nouveau/fb/nv50: Add PFB writes") This fix a GPU lockup on 9400M (NVAC) when using acceleration, see https://bugs.freedesktop.org/show_bug.cgi?id=27501 v2: - Move code to subdev/fb/nv50.c as suggested by Roy Spliet; - Remove arbitrary writes to 100c18/100c24 - Replace write to 100c1c of arbitrary value by the address of a scratch page as proposed by Ilia

Here's a quick-but-I-guess-tidy-fix for faulty behaviour someone reported in NVAF. I'm just not sure if the check for nvaa/nvac should still be in nv50_pm_clocks_pre... I believe this is wrong as they can reclock perfectly well (except the non-existing memory). Anyone has a definite answer to that?

Hey Ilia, I think I've expressed my thoughts on this previously via IRC, but let me stick them here too so there's a record
