hwmon: (ftsteutates) Replace fanX_source with pwmX_auto_channels_temp
Replace the nonstandard fanX_source attributes with the standardized pwmX_auto_channels_temp attributes and document the special behaviour associated with those attributes. Tested on a Fujitsu DS3401-B1. Signed-off-by: Armin Wolf <W_Armin@gmx.de> Link: https://lore.kernel.org/r/20230105225107.58308-3-W_Armin@gmx.de Signed-off-by: Guenter Roeck <linux@roeck-us.net>

8 fans. It also contains an integrated watchdog which is currently
implemented in this driver.
+The ``pwmX_auto_channels_temp`` attributes show which temperature sensor

The 4 voltages require a board-specific multiplier, since the BMC can
only measure voltages up to 3.3V and thus relies on voltage dividers.
Consult your motherboard manual for details.
