Brownout Detection is detected during the boot sequence. If the previous shutdown resulted in a reboot reason that has *ocp* or *uvlo* in it, the shutdown was due to brownout. Mitigation Logger should have logged the device state during the brownout. This event metric is to surface the logged data. Bug: 250009365 Test: Confirm triggering of events Signed-off-by: George Lee <geolee@google.com> Change-Id: Ib142a4135d0a9ff617fc8355f0ba978b5c3f8afb
