Refactor temperature sensor code and add support of Link I2C temp sensor.
Refactor board/chip-specific code into corresponding directories.
Add support of the four I2C temp sensor in Link.
Use table lookup to handle different types of temperature sensors.
BUG=chrome-os-partner:7527
TEST=Correctly read EC internal temperature on bds.
Compile for link succeeded.
