    drm:pl111: Add of_node_put() when breaking out of for_each_available_child_of_node()
    
    [ Upstream commit e0686dc6f2252e009c455fe99e2ce9d62a60eb47 ]
    
    The reference 'child' in the iteration of for_each_available_child_of_node()
    is only escaped out into a local variable which is only used to check
    its value. So we still need to the of_node_put() when breaking of the
    for_each_available_child_of_node() which will automatically increase
    and decrease the refcount.
