wspoon: Remove GPU power sensors

The power values being displayed were basically instantaneous
readings as measured by the APSS monitor device, and as such
could show a lot of peaks and valleys that would be undesirable
to surface.

In the future they may get added back in with some averaging done.

In the meantime, the user can use the nvidia-smi command line tool
on the host to get the proper power values.

Tested:  No GPU power sensors in D-Bus.

Resolves openbmc/openbmc#3183
