nvidia-gpu: add Power Sensor PeakReading Property
Add support for Sensor Properties PeakReading and PeakRedingTime.
Current Limitation -
The ResetMetrics action is currently not supported for Redfish URIs in
bmcweb. As a result, the ability to clear PeakReading values for GPU
Power Sensors has not been implemented.
Future Consideration -
If ResetMetrics action support is added to bmcweb in the future, the
corresponding functionality will also need to be implemented in the
dbus-sensor application to ensure full compatibility.
Tested: Build an image for gb200nvl-obmc machine with the following
patches cherry picked. This patches are needed to enable the mctp stack.
