Hi!

Yet another LM75 temperature sensor. Add it to the list of
supported chips.

Changes since v1:
- disable "flowed" text messages in thunderbird, and hopefully get
  clean patches this time (first patches sent since I got a new
  computer)     sorry about that      *blush*
- add tag from Rob Herring

Cheers,
Peter

Applied to hwmon-next.

Thanks,
