[PATCH 4.19 68/74] of: Convert to using %pOFn instead of device_node.name

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rob Herring <robh@kernel.org>

commit a613b26a50136ae90ab13943afe90bcbd34adb44 upstream.

In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.
