hw-mgmt: infra: Optimize PSU init time

For PSU on udev event we have a delay 2 sec which is needed to allow PSU controller to stabilize. This delay of 2 sec can be too much. In this change, we replaced constant delay to PSU attribute polling, which can help us to get the exact time when PSU is ready and reduce wait time for PSU attributes init.
