Given the memory mapped IO space available in arm64, these windows can be increased substantially to support more use cases. The change increases the 32-bit window to 256MB and the 64-bit window to 128 GB. The firmware on vulcan boards will use these ranges as well. PCI IO windows are not supported on Vulcan, so remove them instead of keeping an unused value.
