power: pm8921-bms: fix override mode causes sleep current increase
The override mode is used to measure battery voltage and current
simultaneously. We observed that the XOADC and the AMUX
were left enabled even after the override mode is exited. This
causes the current consumption to increase by 500uA.
Execute a dummy XOADC read after override mode is exited. This will
ensure that the XOADC and the AMUX get turned off after the dummy
transaction is completed.
