hwmon/f71882fg: Fix temp1 sensor type reporting
The code for determining a sensort type for temp1 was based on me misreading
the datasheet, the tested registers do not determine what kind of sensor
is actually reported as temp1. Instead the enable / disable certain additional
digital sensor readouts throug PECI / AMDSI, etc. Independent of these settings
temp1 is still reading an external BJT or thermistor as configured by the
Temperature Sensor Type Register (0x6b).
