ioread32() is indeed an alias for readl on arm64 but if the address it
gets as argument looks like an I/O port, it adds PCI_IOBASE (via the inl
macro). This would no longer happen with Thierry's patches.

So I guess that for this patch to work, we also need ioport_map() to
return an address from the PCI_IOBASE range. Should we merge this now as
well:

This is also part of patch 1/3 in Thierry's series.

The hunk in my patch 1/3 is missing the "& IO_SPACE_LIMIT", I can respin
and include that.
