This adds a fixed virtual mapping for PCI i/o addresses. The mapping is located at the last 2MB of vmalloc region (0xfee00000-0xff000000). 2MB is used to align with PMD size, but IO_SPACE_LIMIT is 1MB. The space is reserved after .map_io and can be mapped at any time later with pci_ioremap_io. Platforms which need early i/o mapping (e.g. for vga console) can call pci_map_io_early in their .map_io function. This has changed completely from the 1st implementation which only supported creating the static mapping at .map_io.
