    dtc: Reinstate full old-style reference-to-path for v0 dts files
    
    Commit 7c44c2f9cb1cc2df7aacd13decfc4e64b73d1730 broke backwards
    compatibility more badly than I realised.  Contrary to what I thought
    there are in-kernel, in-use dts files which relied on
    references-to-path with paths including a comma, which no longer
    compile after that commit.
    
    So, this patch reinstates full support for bare references-to-path in
    dts-v0 input.  This means there will be some rather surprising lexical
    corner cases when using path-expanded references in v0 files.  But,
    since path-expanded references are new, v0 files shouldn't typically
    be using them anyway.  If the corner cases cause a problem, you can
    always convert to dts-v1 which handles the lexical issues here more
    nicely.
