nvidia-gpu: add TLimit sensor
This commit introduces a new thermal limit (TLimit) sensor for the GPU,
enhancing the existing temperature monitoring capabilities.
Tested: Build an image for gb200nvl-obmc machine with the following
patches cherry picked. This patches are needed to enable the mctp stack.
