Remove the witherspoon prefix from the PSU monitor

The Swift system is a follow-on to the Witherspoon system. The plan is
to re-use the power supply monitor application on Swift, while
continuing to work on Witherspoon systems. Removing the witherspoon
prefix from the app to avoid confusion.

Tested: Built and flashed image to Witherspoon system. Verified power
sequencer and power supply monitor logged errors via 'obmcutil
chassiskill' command.
