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.
The child nodes within mvpp2_probe are not accessed outside the lopps,
and the socped version of the macro can be used to automatically
decrement the refcount on early exits.
Use `device_for_each_child_node()` and its scoped variant to indicate
device's direct child nodes.
