wspoon: Enable fan floor adjustments based on mode

Add actions to adjust the fan floor speed table used based on the
thermal mode of the system. In addition to adjusting the fan floor speed
table, in some modes the default fan floor required adjustment as well.

These fan floor speed values and the corresponding default fan floor
speed per mode were provided by the thermal characterization team.
