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).
