    Print Ampere+ device_info fields with correct offsets/widths

    Everything now has been checked against how nvgpu handles it

    Rearrange, fix an off-by-one error, and remove an unused define

    The code in nvdebug.h has been rearranged to enable an easier merge
    against the jbakita-wip branch.
