First patch fixes a potential vbios parsing bug on Fermi GPUs, but it may also affect Kepler ones. Second patch wakes the GPU up whenever the user tries to reclock to prevent the write to the pstate file from freezing.

Adds Nouveau controlled thermal throttling for Kepler+ GPUs. With this I feel safe enough to add support for Maxwell2 reclocking later on (still hidden behind a switch, but we can be fairly sure to not overheat hardware if a user isn't carefull enough) Contains all patches from my clk update series, but I thought it makes sense to include those in this series as well for completness. Please
