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.

It is possible to bypass the voltage attenuators on the +2.5V, Vccp,
+5V and +12V voltage monitoring inputs. This is useful to connect
other voltage channels than the ones the monitoring chip was
originally designed for. When this feature is enabled, we must not
include the scaling factors in our computations.

The TACH4 pin can be used for other functions, so fan4 may not always
be available. Likewise, the PWM2 pin can be used for ALERT output, in
which case pwm2 is not available

For the ADT7490, the +2.5 Vin pin may also be used for other
functions, in which case in0 is not available.

Move sysfs files removal to a separate function. The code is common to
the device probing error path and the standard device removal path. As
it will grow with future driver development, this avoids code
duplication.

New documentation for the adt7475 driver, based on the adt7473 driver

Add support for the ADT7473 to the adt7475 driver, and mark the
adt7473 driver for removal. The ADT7473 and ADT7475 chips are almost
the same chip and essentially compatible, so there's no point in
having separate drivers for them.

This adds support for the Fintek f71889fg to the f71882fg driver,
many thanks to Gerd v. Egidy for providing (remote) access to a
machine which such an ic.

Note that this bit of the patch:
-	val = SENSORS_LIMIT(val, 0, 255);
+
+	if (data->type == f71889fg)
+		val = SENSORS_LIMIT(val, -128, 127);
+	else
+		val = SENSORS_LIMIT(val, 0, 127);

Changes behaviour for already supported models, the new behaviour is correct
as the already supported models have bit 7 of the involved registers fixed at
0, so the previous behaviour which allowed setting temp zone limits > 127
was not correct.

There is a bug in the old sysfs file removal, as it uses fxxxx_in_temp_attr
to remove the in and temp sysfs attributes, but fxxxx_in_temp_attr has
temp#_alarm, where as f71858fg_in_temp_attr has temp#_max_alarm, so
the temp#_max_alarm attributes for the f71858fg never get removed.

This patch fixes this by doing the sysfs removal exactly the same way as
the creation instead of being (too) clever, this will also avoid similar
bugs in the future.

This patch merges the f71882fg_auto_pwm_attr array into the
fxxxx_fan_attr resp. fxxxx_auto_pwm_attr array, as the f71882fg_auto_pwm_attr
array was merely extending these 2 with entries for a 4th fan, it also makes
these 2 arrays 2 dimensional so that the rest of the code can choose to
add attr for 3 or 4 fans without needing to know the nr of attr per fan.

This patch makes a number of cleanups to the sysfs attr creation
in the f71882fg driver, this is a preparation patch for adding f71889fg
support:

* Add some comments to explain why some models need separate sysfs attr
  arrays for in / temp / fan / pwm
* Rename a number of sysfs attr arrays to make their function clearer
* Move the pwm#_auto_channels_temp attribute from the common to all
  models fan attr array to the per model auto mode pwm attr arrays, so
  that all the auto mode pwm attr are grouped together, and thus can be
  left out on models where we don't support auto pwm mode
* Put fan_beep attr in their own array, so that only auto mode pwm attr
  remain in the per model pwm sysfs attr arrays.
* Put the 4th special fan input for the f8000 in its own array, so that only
  auto mode pwm attr remain in the per model pwm sysfs attr arrays.
