dt-bindings: mfd: add entry for the Marvell 88PM88X PMICs

Marvell 88PM880 and 88PM886 are two similar PMICs with mostly matching
register mapping and subdevices such as onkey, regulators or battery and
charger. Both seem to come in two revisions which seem to be handled
slightly differently in some subdevice drivers.
