In order to allow the use of PCIe cards such as graphics cards, whose demands for BAR space are typically much higher than those of network or SATA/USB cards, reconfigure the I/O windows so we can declare two MMIO PCI regions: a 512 MB MMIO32 one at 0xc000_0000 and a 4 GB MMIO64 one at 0x8_0000_0000. In addition, this will leave ample room for an ECAM config space at 0xe000_0000 (up to the ECAM maximum of 256 MB) For compatibility with older kernels or firmware, leave the original 16 MB window in place as well.
