baytrail: add south cluster fixed resources

Browse Source 
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.

BRANCH=None
TEST=Built and booted through depthcharge. Verified
     resource allocation not weird. And no more depthcharge
     crashes.
