Add retries into power control status commands

On first boot we're seeing an occasional miss of the
power status, but the match never being fired. This seems
to be caused by the sensors overwelming power control
by requesting too often. Add in a couple retries to
make sure we get the status.

Tested: On system with 100% production rate, cpu sensor
readings were valid

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
