[Nouveau] [PATCH 8/9] clk: export nvkm_volt_map

[Karol Herbst]

we need this later to see which cstate can be actually used, because the
set voltage for a cstate actually exceed the maximum possible voltage of the
gpu.

We want to know that in the clk subdev so that we do not try to set such a
cstate
