power: smb-lib: Restart charging from soft JEITA

In the scenario where the charging is terminated in the
JEITA soft condition, the HW is expected to restart
charging when battery temperature returns back to normal.

However, this does not work as expected and the charging
stays terminated. Fix this by disabling and re-enabling
charging CMD bit to restart charging.
