PCI: apple: Use helper function for_each_child_of_node_scoped()

Browse Source 
[ Upstream commit f60b4e06a945f25d463ae065c6e41c6e24faee0a ]

The for_each_available_child_of_node_scoped() helper provides
a scope-based clean-up functionality to put the device_node
automatically, and as such, there is no need to call of_node_put()
directly.

Thus, use this helper to simplify the code.
