link: Temp sensors can return not-powered error code

This removes the need for a separate method to check sensor power, and
gets rid of temp_sensor.c knowledge of what powers each sensor.

BUG=chrome-os-partner:15174
BRANCH=link
TEST=manual

- reboot
- within a second, type 'temps'; I2C sensors should return error 1
- type 'temps' again; all sensors should return data
- power off system
- type 'temps' again; I2C sensors and PECI should return error 8
- 'gpioset enable_vs 1'
- type 'temps' again; I2C sensors should return valid data; PECI should still
  return error 8.
