Add support for the w83627ehf thermal sensor types. I made them read-only,
as the BIOS is supposed to set them up properly. This information makes it
easier to find out which temperature channel corresponds to the CPU.

The W83627EHF and similar chips have 6 VID input pins, add support
for them. The driver changes the input voltage level automatically
if the current setting is not correct for the detected CPU model.

* I have experimental evidence that the W83627EHG needs more than 1
second to refresh all the measured values. Increase the caching time to
1.5 second.
* When changing a fan clock divider, the corresponding fan speed
measurement register is no longer valid, until the next time the chip
will refresh it. One way to fix this is to pretend that the cache is
still valid for one more period (1.5 second.)

If the Super-I/O device is disabled, it is likely the BIOS has a good
reason for leaving it disabled, so give a warning when enabling it --
it's not likely to be wired correctly or be able to give good data.
Also, if the Super-I/O device is configured with an address of 0, the
driver refuses to initialize it.

This patch adds a new driver for the hardware monitoring features of the
third revision of the Abit uGuru chip, found on recent Abit
motherboards. This is an entirely different beast then the first and
second revision (its again a winbond microcontroller, but the "protocol"
to talk to it and the bank addresses are very different.

Add support for the "temperature mode" fan speed control. In this mode,
the user can define 3 temperature/speed trip points, and the chip will
set the speed automatically according to the temperature changes.

The w83627ehf driver changes the fan clock divider automatically when
a new min fan speed is set. It is supposed to preserve the fan speed
reading while doing so, bug doesn't really. Fix it.

Fix a potential race condition when some hardware monitoring platform
drivers are being unloaded. I believe that the driver data pointer
shouldn't be cleared before all the sysfs files are removed, otherwise
a sysfs callback might attempt to dereference a NULL pointer. I'm not
sure exactly what the driver core protects drivers against, so let's
play it safe.
While we're here, clear the driver data pointer when probe fails, so
as to not leave an invalid pointer behind us.
