siemens/sitemp_g1p1: Make ACPI report the right mmconf region

ACPI reported the entire space between top-of-memory and some
            (relatively) arbitrary limit as useful for MMIO. Unfortunately
            the HyperTransport configuration disagreed. Make them match up.

Other boards are not affected since they don't report any region
            for that purpose at all (it seems).

It sneaked in without it's dependencies and, therefore, broke the build for
    all amdk8 targets. Paul Menzel already commented on the issue in [1]. It
    also doesn't look like the dependencies would be pulled soon [2].
