commit c4cb12e193e314226991deb468c1b397296dea53

    Alter grammar to allow multiple /dts-v1/ tags
    
    This patch allows dtc to accept multiple /dts-v1/ tags (provided they're
    all at the beginning of the input), rather than giving a syntax error.
    
    This makes it more convenient to include one .dts file from another without
    having to be careful that the /dts-v1/ tag is in exactly one of them.
    
    We a couple of existing testcases to take advantage of this, which
    simplifies them slightly.
