Fixes Units for Temperature & Pressure for Hwmon

For pressure the units are Pascals and was missing in SensorPaths.cpp
Also changed to align with the rest of dbus-sensors and set units
as sensor_paths::unitDegreesC and sensor_paths::unitPascals instead
of literal string constants.

Tested: on Everest's Storm King Op Panels with busctl introspect \
--no-pager xyz.openbmc_project.HwmonTempSensor /xyz/openbmc_project/\
sensors/temperature/Ambient_1_Temp and with
busctl introspect --no-pager xyz.openbmc_project.HwmonTempSensor \
/xyz/openbmc_project/sensors/pressure/Station_Pressure
the .Unit fields are now align with the rest of dbus-sensors

dbus-sensors

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.

key features

  • runtime re-configurable from d-bus (entity-manager or the like)

  • isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible

  • async single-threaded: uses sdbusplus/asio bindings

  • multiple data inputs: hwmon, d-bus, direct driver access
