    Use PCIOCREADMASK on OpenBSD.
    
    If the machdep.allowaperture sysctl(8) variable is set to 0, writing to PCI
    config space is not allowed.  So instead of writing 0xffffffff to the BARs
    in order to determine their size, use the PCIOCREADMASK ioctl(2) which
    returns the mask of changeable bits that was saved by the kernel when the
    devices was initially probed.
