Subject: [PATCH 2/2] mfd: arizona: Destroy regulators after the other MFD cells

Several of the cells depend on the regulators provided by the
arizona-micsupp and arizona-ldo1 cells. As such use the new remove_level
feature of the MFD core to ensure the regulators are destroyed after all
the other cells.
