gpu: nvgpu: init: skip failing probe if therm DT entry is absent

Browse Source 
For dGPU with PCIE interface do not have a thermal alert pin.
Only platforms where dGPU is used with SXM interface have the
thermal alert pin.
This change makes sure that if nvgpu-therm-gpio DT entry is
is missing we don't fail probe but continue with GPU
initialization without enabling thermal alert feature.
