hwmon: (sch5627) Add pwmX_auto_channels_temp support
After doing some research, it seems that Fujitsu's
hardware monitoring solution exports data describing
which temperature sensors affect which fans, similar
to the data in fan_source of the ftsteutates driver.
Writing 0 into these registers forces the fans to
full speed.
Export this data with standard attributes.
