Add Group Event Support for PSU

Some group events such as PSU Fan Fault will only have one event but
have more than one target to trigger redfish log. For example, PSU Fan
only has one event PSU Fan Fault, any Fan failure will trigger PSU Fan
Fault and change the functional property to false. But if another PSU
Fan failure happens, we still need to trigger a redfish log to indicate
the specific fan number. So change the PSU Event logic to support this
feature.

Tested:
Remove one of the PSU, Redfish Log show PSU Fan Fault on Fan1 and Fan2.
Insert the PSU and Redfish Log show PSU Fan1 and Fan2 recovered.

dbus-sensors

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.

key features

  • 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
