sb/amd/sr5650: Correctly locate CPU MMCONFIG resource

The code committed in GIT hash
     * 1eaaa0 southbridge/amd/sr5650:Add MCFG ACPI table support
    did not correctly locate the CPU MMCONFIG resource, leading to failures
    with operating systems and firmware (e.g. SeaBIOS) when the PCI
    extended configuration space option was activated.

Due to the southbridge routing not being set up, MMCONFIG accesses were
    targetting DRAM and therefore the PCI devices were not being configured.
    The failure normally manifests as a system hang immediately after PCI
    configuration starts.

Search for the CPU MMCONFIG resource on all domains below the root
    device.
