Laszlo Ersek b01acf6ea7 OvmfPkg: PlatformPei: lower the 32-bit PCI MMIO base to 2GB on Q35
Gerd has advised us that long term support Q35 machine types have no low
RAM above 2GB, hence we should utilize the [2GB, 3GB) gap -- that we
currently leave unused -- for MMIO. (Plus, later in this series, for the
PCIEXBAR too.)
