Make ACPI code detect Sandy/Ivy Bridge dynamically
On systems with socketed CPUs we want to be able to
drop in a Sandy Bridge or Ivy Bridge CPU without recompiling the
firmware. Hence, detect the north bridge dynamically. In order
for this to work, we need Ivy Bridge MRC and coreboot configured
for Ivy Bridge.
