mfd: ab8500-sysctrl: Update correct turn on status

Browse source

In L9540, turn_on_status register is not updated correctly if
the device is rebooted with AC/USB charger connected. Due to
this, the device boots android instead of entering into charge
only mode. Read the AC/USB status register to detect the charger
presence and update the turn on status manually.
