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.
