[PATCH 5/6] leds: pca995x: use device_for_each_child_node() to access device child nodes

[Javier Carrasco <javier.carrasco.cruz@gmail.com>]

The iterated nodes are direct children of the device node, and the
`device_for_each_child_node()` macro accounts for child node
availability.

`fwnode_for_each_available_child_node()` is meant to access the child
nodes of an fwnode, and therefore not direct child nodes of the device
node.

Use `device_for_each_child_node()` to indicate device's direct child
nodes.
