platform/chrome: cros_ec: Notify the PM of wake events during resume 

cros_ec_handle_event in the cros_ec driver can notify the PM of wake
events. When a device is suspended, cros_ec_handle_event will not check
MKBP events. Instead, received MKBP events are checked during resume by
cros_ec_report_events_during_suspend. But
cros_ec_report_events_during_suspend cannot notify the PM if received
events are wake events, causing wake events to not be reported if
received while the device is suspended.

Update cros_ec_report_events_during_suspend to notify the PM of wake
events during resume by calling pm_wakeup_event.
