SENSORS_LIMIT and the generic clamp_val have the same functionality,

Many hwmon drivers use jiffies but omit the inclusion of the header
file. Fix that, and also fix one driver which was including the header
file but didn't need it.

This patch converts the drivers in drivers/hwmon/* to use the
module_i2c_driver() macro which makes the code smaller and a bit simpler.

We can mark normal_i2c const. Almost all drivers do that already, so
fix the 3 remaining ones before they are used as (bad) examples for
new drivers.

These macros simply declare an enum, so drivers might as well declare
it themselves. This puts an end to the arbitrary limit of 8 chip types
per i2c driver.

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.

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.

I can't believe this has been broken since the driver was added, 8
