Since the QMP driver split there will be at most a single child node so drop the obsolete iteration construct. While at it, drop the verbose error logging that would have been printed also on probe deferrals. Note that there's no need to check if there are additional child nodes (the kernel is not a devicetree validator), but let's return an error if there are no child nodes at all for now.
