[PATCH 1/2] gpio: don't process hogs on disabled nodes

[Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>]

The core hogging logic uses device_for_each_child_node_scoped(), which
iterates over all child firmware nodes without checking their
availability. Before the code was moved to the GPIO core, it correctly
used for_each_available_child_of_node_scoped() to skip disabled nodes.
Check if the node is available and skip it if not.

Closes: https://sashiko.dev/#/patchset/20260608210108.36248-1-dan%40reactivated.net
Fixes: d1d564ec4992 ("gpio: move hogs into GPIO core")
