input: pm8xxx-vibrator: refactor to support new SPMI vibrator

Currently, vibrator control register addresses are hard coded,
including the base address and offsets, it's not flexible to
support new SPMI vibrator module which is usually included in
different PMICs with different base address. Refactor it by using
the base address defined in devicetree.
