hwmon: (adt7475) document mapping of sysfs entries to inputs
As per the usual standard with hwmon drivers the mapping to sysfs entries follows the register map of the device e.g. in0_input corresponds to the register 0x20, in1_input corresponds to 0x21 etc. Hardware designers tend to work with input pins instead of registers which is where things start to get confusing. A hardware designer might say "the 1.5V rail is connected to the VCCP pin" leaving the software designer none the wiser as to which of the sysfs entries should be associated with the label "1.5V". Try to bridge the gap by documenting the mapping of sysfs entries to the corresponding pins. This should allow someone to create a configuration file or other mapping without needing to dive into the code and ADT datasheets.
