[PATCH v2] dt-bindings: gpio: mpfs-gpio: allow parsing of hog child nodes.

[PATCH v2] dt-bindings: gpio: mpfs-gpio: allow parsing of hog child nodes.

[Conor Dooley]

The SD card and eMMC on PolarFire SoC are sometimes muxed using a GPIO
by the bootloader. Add a hog child property to facilitate this.

Changes since v1:
- move addtionalProperties up under type:
