Required properties:
-- compatible : Should be "marvell,orion-gpio", "marvell,mv78200-gpio"
- or "marvell,armadaxp-gpio". "marvell,orion-gpio" should be used for
- Orion, Kirkwood, Dove, Discovery (except MV78200) and Armada
- 370. "marvell,mv78200-gpio" should be used for the Discovery
- MV78200. "marvel,armadaxp-gpio" should be used for all Armada XP
- SoCs (MV78230, MV78260, MV78460).

- reg: Address and length of the register set for the device. Only one
entry is expected, except for the "marvell,armadaxp-gpio" variant
for which two entries are expected: one for the general registers,
- one for the per-cpu registers.
+ one for the per-cpu registers. Not used for marvell,armada-8k-gpio.
- interrupts: The list of interrupts that are used for all the pins
managed by this GPIO bank. There can be more than one interrupt
