Adding label files for fan and temperature sensors in the power supply.
The openbmc application dbus-sensor(psusensor) requires those files to
consfigure those sensors.
Note that prefix for temp label is temp[A..C] used instead of temp[1..3]
as dbus-sensor(psusensor) application calculate index based on last
digit in the name so we do not want to make index double digit after
appending page index.
