    dtbtool: Add support for array of ID's in qcom,msm-id tag

    Allow multiple chipset/platform/soc_rev triplets in
    qcom,msm-id tag.  This allows one DTS/DTB file to be used
    for multiple chipset/platform/soc_rev variants.

    Preliminary version - needs error handling in triplet
    parsing and general code cleanup.
