    Use pci_io_write8 instead of outb · c1e88427

    This ensures better portability as some arches (eg aarch64) don't have
    outb.
    On linux pci_io_* try to open the sysfs map file corresponding to the
    I/O port range, which the kernel translates arch-appropriately.  If
    there is no such file then it'll try to use port instructions if that's
    a thing the architecture has.  So you only need one path, pciaccess
    exists to get the portability right for you.
