Subject: [PATCH v4 3/3] dt-bindings: gpio: gpio-mvebu: document offset and marvell,pwm-offset

The offset and marvell,pwm-offset properties weren't in the old binding.
Add them based on the existing usage in the driver and board DTS when
the marvell,armada-8k-gpio compatible is used.

Notes:
    Changes in v4:
