Show the fan-cooling percentage for each active temp sensor
When displaying the temps, if the sensor has valid entries to
control the target fan speed, show them. This lets us see which
sensor is the main player in the cooling needed without doing a
bunch of math.
BUG=none

Then, before this CL:

PECI : 308 K = 35 C
ECInternal : 309 K = 36 C
I2C-Charger-Die : 307 K = 34 C
I2C-Charger-Object : Not calibrated
I2C-CPU-Die : 304 K = 31 C
I2C-CPU-Object : Not calibrated
I2C-Left C-Die : 302 K = 29 C

I2C-Right D-Object : Not calibrated
I2C-Left D-Die : 306 K = 33 C
I2C-Left D-Object : Not calibrated
After this CL:
