nvidia-gpu: add SMA Temperature Sensor
Add support for device type SMA (System Management Agent) and its
temperature sensor. It is typically an MCU device.
Tested: Build an image for gb200nvl-obmc

nvidia-gpu: introduce notion of a device
Perform device discovery tasks only once per device to prepare for
introducing additional gpu sensors.
In the current implementation, sensor updates and device discovery via
MCTP are managed within a single class for simplicity. However, since a
GPU device typically includes multiple sensors, performing device
discovery for each individual sensor is inefficient. Instead, it would
be more effective to execute device discovery once per device.
Tested: Build an image for gb200nvl-obmc machine with the following
patches cherry picked. This patches are needed to enable the mctp stack.
