hwmon: (adt7475) Add support for the ADT7476
Add support for the Analog Devices ADT7476 chip. This chip is largely
compatible with the ADT7473 and ADT7475, with additional features.
In particular, it has 5 voltage inputs instead of 2, and VID input
pins.

Description
-----------
-This driver implements support for the Analog Devices ADT7473, ADT7475 and
-ADT7490 chip family. The ADT7473 and ADT7475 differ only in minor details.
-The ADT7490 has additional features, including extra voltage measurement
-inputs and PECI support. All the supported chips will be collectively
-designed by the name "ADT747x" in the rest of this document.
