Thanks for updating BayleyBay dts as well :)

One general comment: I think we should replace these hardcoded numbers
with meaningful macros (eg: 0x800 means MMIO uses 2GB space, that's
why we see previous the pci does not work on a 4GB DIMM as FSP only
maps 2GB RAM per this setting). See Intel's Baytrail_FSP_Gold4.tgz
release FSP/BayleyBayFsp.bsf file, it has the details of how each
magic number maps to what meaning. Will you do a follow-up patch for
this? I can do that as well.
