power: smb5: Turn off charging if wdog is not petted 



In the event of a catastrophic software freeze, the watchdog does not
get petted when it barks. As per design, in such a scenario, it waits
for a pre-configured period of time and then bites, turning off battery
charging.

Currently, battery charging is not turned off. Enable turning off of
battery charging when the watchdog bites.
