Speed up the boot time of PSU Sensors Currently, on some PSU, PSU Sensor daemon will take very long time to work stably, and it needs very long time before PSU Sensor daemon can provide all D-Bus interface for PSU Sensors. Since all PSU label in sysfs will not stay in subdirectory, no need to use findFiles to check label files since findFiles will cost a lot of time. Tested: Run ipmitool sensor list, all PSU sensors will show correctly. Pid Control service will not restart again and again owing to PSU Fan Speed D-Bus interface not ready.

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
