hwmon: (w83627ehf) Add W83627DHG-P support

Add support for the new incarnation of the Winbond/Nuvoton W83627DHG
chip known as W83627DHG-P. It is basically the same as the original
W83627DHG with an additional automatic can speed control mode (not
supported by the driver yet.)

The DHG also supports PECI, where the DHG queries Intel CPU temperatures, and
the ICH8 southbridge gets that data via PECI from the DHG, so that the
southbridge drives the fans. And the DHG supports SST, a one-wire serial bus.
The DHG-P has an additional automatic fan speed control mode named Smart Fan
(TM) III+. This mode is not yet supported by the driver.
