PCHG: Send device event to host
This patch makes PCHG send EC_HOST_EVENT_DEVICE on every state
machine cycle. The host is expected to retrieve the device
event mask through EC_CMD_DEVICE_EVENT and updates port status
if the mask has EC_DEVICE_EVENT_WLC.
BUG=b:173235954
BRANCH=Trogdor
TEST=Enabled and disabled EC_DEVICE_EVENT_WLC via deviceevent
command and verified the sysfs node is updated.
