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.

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.
runtime re-configurable from d-bus (entity-manager or the like)
isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible
async single-threaded: uses sdbusplus/asio bindings
multiple data inputs: hwmon, d-bus, direct driver access
