sim, power: Temperature used for power calculations
The temperature used for the power calculations was fixed at 0
degrees, unless a thermal model was setup. This commit allows
the user to set the temperature that needs to be used by the
power calculation during gem5 configuration. This value will be
overwritten if there are thermal models present.
