nvidia-gpu: add dram temperature sensor
This commit introduces a dram temperature 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.
