    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.

dtbtool: add new --dt_tag switch

* Add new switch named --dt_tag (or -d)
* Allows a custom QCDT_DT_TAG
* If --dt_tag/-d is not used, it defaults to "qcom,msm-id =<" as it is today.

This should allow more flexibility with devices requiring various DT_TAGs going forward.
