The dts syntax allows for '<>' around phandles and arg cells or not
which it didn't matter until adding type information. However, the YAML
encoding expects each phandle + args to be bracketed.
If TYPE_UINT32 markers are not present before each REF_PHANDLE, fix up
the markers and add the TYPE_UINT32 markers. This allows the subsequent
YAML emitting code to work as-is.
Adding the markers at an earlier stage doesn't work because of
possible labels in dts output. We'd have to define the ordering of
labels and brackets. Also, it is probably best to have dts output match
the input.
