msm: qpnp-power-on: Store device shut down in PMIC register



Use the control register in PMIC power-on peripheral store device
in the shut down state. If an user initiates a shutdown from
user space by pressing the power key, (in the case of this particular flag)
ON means that the device will stay in shut down state instead of shut down
and boot device again.
