ioperm and pseudo devices

[Marcus Brinkmann]

Hi,

I think we need a flag in the device structure to mark the type of the
device more properly than the device ops does.  In particular, I am worried
about someone sending an io perm modify IPC to a non-io perm device port, it
doesn't look to me as if I coded any guard against this into it.

Thanks,
Marcus
