motorola:qpnp-smbcharger-mmi Delay first boot heartbeat

Browse source 
Update charger driver to also delay heartbeat caused by
psy notifier call. Since this is the only other place
that heartbeat can first be called from. We only want to
apply this delay to the first time so we use a static
variable flag. Also add some extra debug just encase.
