Documentation: hwmon: adt7411: document supported sysfs attributes

Browse Source 
The adt7411 driver exposes additional standard hwmon attributes beyond
the ones currently listed in Documentation/hwmon/adt7411.rst.

Document voltage min/max/alarm attributes, temperature min/max and
min_alarm/max_alarm attributes, and the temp2_fault attribute for the
external temperature channel.

Also update the documentation to clarify that analog inputs in1 and in2
are not available when the external temperature sensor is enabled, and
remove the outdated statement claiming that external temperature support
and limit registers are unsupported.
