    Move PCI configuration space, MMIO and memory to the KIO range to free
    vmalloc area and use static TLB to access them. Move MMIO to the
    beginning of KIO and define PCI_IOBASE as XCHAL_KIO_BYPASS_VADDR to
    match it. Reduce number of supported PCI buses to 0x3f so that ECAM
    window fits into first 64MB of the KIO. Reduce size of the PCI memory
    window to 128MB so that it fits into KIO.
