[PATCH v3] dt-bindings: gpio: fsl,qoriq-gpio: allow gpio-hog child nodes

[Vincent Jardin via B4 Relay]

From: Vincent Jardin <vjardin@free.fr>

QorIQ GPIO controllers may have hogs in device nodes, so let's expose
it.

Changes in v3:
- Shorten the commit message, former one tried too much on QorIQ (Krzysztof Kozlowski)
- Drop redundant brackets from the pattern (Krzysztof Kozlowski)
- No change to the schema semantics
- Link to v2: https://lore.kernel.org/r/20260824-for-upstream-dt-qoriq-gpio-hog-v2-1-58bbc82b881e@free.fr

Changes in v2:
- Change the commit message. Drop the dmesg excerpt: those hog names come
  from my out-of-tree dev git repo and are not in the tree (Frank Li)
- Note: the hog call path is: gpiochip_hog_lines(), called from gpiochip_add_data_with_key()
- Explain why these QorIQ SoCs need it
- No change to the diff
- Link to v1: https://lore.kernel.org/r/20260824-for-upstream-dt-qoriq-gpio-hog-v1-1-d75923bcecad@free.fr
