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

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.

Signed-off-by: Conor Dooley <[email protected]>

Changes since v1:
- move addtionalProperties up under type:
- drop the explicit match group syntax
