[RFC PATCH v2 20/74] dtc: Extend complete_references() to handle export symbols

[Herve Codina]

Export symbols parsed from a .dts or .dtb file suffer from the same
incompleteness as REF_PHANDLE markers. They may lack either the
ref string or the is_local flag depending on the device-tree input
format used.

Apply the same completion operation as the one done for REF_PHANDLE
markers.
