[PATCH] I2C: New hardware monitoring driver: w83627ehf

This is a new hardware monitoring driver, w83627ehf, which supports the
Winbond W83627EHF Super-I/O chip. The driver is not complete, but
already usable. It only implements fan speed and temperature monitoring,
while the chip also supports voltage inputs with VID, PWM output and
temperature sensor selection. I have no more time to work on this, but
anyone with supported hardware could add the missing functionalities

This driver is largely derived from the w83627hf driver.

Thanks to Leon Moonen and Steve Cliffe for tesing the preliminary
versions of my driver and reporting the problems they encountered.

Thanks to Grant Coady for noticing and fixing various corner cases in
the fan management. This third version of the driver hopefully addresses
all the issues the original version had.

This driver can also be built as a module. If so, the module

If you say yes here you get preliminary support for the hardware
monitoring functionality of the Winbond W83627EHF Super-I/O chip.
Only fan and temperature inputs are supported at the moment, while
the chip does much more than that.
