Read duration stats expoted by google,usbc_port_cooling_dev and push suez atom when the uevent is received. The plugged temperature is queried every time when the USB port is connected. Maximum temperature during overheat is queried when the uevent is received. Bug: 193615568 Change-Id: Ib02e14dbdbe1390476e864d351158c1523a5c311
