power: qpnp-smbcharger: enable AICL while unpreparing

Currently, the driver ends up writing a 0 to the enable bit when it
wants to enable AICL. This causes AICL to remain disabled and could
cause the input to collapse. Driver should write a 1 to that enable
bit when it wants to enable AICL.

Also it is safe to enable the AICL bit before faking an insertion,
so move the enabling of AICL before that.
