Reading min and max values from the rated files exposed by hwmon

With kernel 5.10 hwmon will expose PSU capabilities files. They will
have endings `_rated_min` and `_rated_max`. This commit allows
PSUSensor to utilize these files. If `rated` files are available
for given sensor then values read from these files will be used to
overwrite the MaxValue and MinValue default values.
The min/max update will be done with frequency 8x times lower than
the sensor value is updated, because in most cases they will not
change too often and for now there is no need to read them more
often.

Tested:
   Test were done manually, no regression detected.
   CPU usage stays at the same level.
   Min and max values are updated properly.
