Add witherspoon hardware sensors for SDR mapping to DBus objects

The handcoded harware sensor yaml file is merged with the final
sensor yaml file.

phosphor-ipmi-sensor-inventory native recipe finds all the
yaml files with extension ".hardcoded.yaml" and merges them
to the final sensor yaml file

Resolves openbmc/openbmc#2613
