This was previously done in a board-specific function across 4 boards.
Except that the board-specific function was identical in all cases
(that is, not really board-specific). Put it back in the common
implementation to get rid of duplicated code, and use
CONFIG_TEMP_SENSOR_POWER_GPIO to indicate which GPIO rail controls the
sensor power.
