baytrail: add south cluster fixed resources

Hardware / Coreboot - Aaron Durbin [chromium.org] - 17 February 2014 11:50 UTC

The PCU (platform controller unit) contains the resources and IP blocks that used to reside in the south bridge. Bay Trail has since renamed it south cluster. There are quite a few fixed MMIO and I/O resources. If these aren't added the resource allocator will freely assign these addresses which causes conflicts and other subtle bugs.

BUG=chrome-os-partner:23544 BUG=chrome-os-partner:23545 BRANCH=None TEST=Built and booted through depthcharge. Verified resource allocation not weird. And no more depthcharge crashes.
