[Nouveau] [PATCH] subdev: add a pfuse subdev v2
Martin Peres

Mon Aug 25 15:26:38 PDT 2014
We will use this subdev to disable temperature reading on cards that did not
get a sensor calibration in the factory.
v2:
- rename "nouveau_fuse_rd32" to "gxXXX_fuse_rd32" as adviced by Christian Costa
- fold the code a little as adviced by Emil Velikov
