v3: Move chip detection for various TMP4xx chips to its own function
Add TMP400 detection
The new detection function was tested with TMP401, TMP411A, TMP431, TMP432,
and TMP435.
Note: Register dumps for the tested chips are available from
https://github.com/groeck/module-tests.git in the register-dumps directory.
