r8169: remove redundant hwmon support

Browse source 
The temperature sensor is actually part of the integrated PHY and available
also on the standalone versions of the PHY. Therefore hwmon support will
be added to the Realtek PHY driver and can be removed here.

Fixes: 1ffcc8d413 ("r8169: add support for the temperature sensor being available from RTL8125B")
