qpnp-smb2: Ignore status 7 register while qnovo is enabled 



status7 register will indicate all the charger bits are cleared during
the rest or discharge phase of a Qnovo pulse. Moreover those bits remain
cleared after a pulse train is done and before a new pulse train is
issued.

Hence when Qnovo is active ignore status 7 register bits.
