[PATCH 4/4] leds: as3645a: use device_* to iterate over device child nodes

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

Drop the manual access to the fwnode of the device to iterate over its
child nodes. `device_for_each_child_node` macro provides direct access
to the child nodes, and given that the `child` variable is only required
within the loop, the scoped variant of the macro can be used.

Use the `device_for_each_child_node_scoped` macro to iterate over the
direct child nodes of the device.
