power: qcom: smb5-lib: Update charging status for handling Qnovo 



Currently, whenever the charging status register shows that the
charging is paused, charger driver shows it as not charging.
In case of Qnovo, this could be due to a momentary pause of
charging. Hence, read charging pause command register to see if
the charging pause is requested and update the charging status.
