As always thanks for your time, Neil.
Not really I was expecting still not working (I am loosing my faith :-)) but
avoid the first WARN_ON and see if root resources were properly listed using
the v8 code which I think is better. Anyway, the problem is with the io resource.
When we call the function to get the resources 'devm_of_pci_get_host_bridge_resources'
this ends up in a 'for_each_of_pci_range' parsing every range in the device tree
and trying to get a resource from it calling to 'of_pci_range_to_resource' function.
This function fails for the IO resource because of the call to 'pci_address_to_pio(range->cpu_addr);'
with an address (0x1e160000) which is greater than IO_SPACE_LIMIT (0xFFFF)
setting a 'OF_BAD_ADDR' for 'start' and 'end' in the resource and
returns EINVAL which is get by 'devm_of_pci_get_host_bridge_resources' to just
don't add the resource to the list and 'continue' with the next range (without failing).
So the difference with previous v7 and lower PATCHes version is that the system does not hang because
probably the increase of the ioport_resource (parent) memory range end limit to
0xFFFFFFFF. Why the legacy code works? Just because it just adds the range as a valid
resource and directly remaps to kernel virtual space the 'range.cpu_addr' to avoid the problem
when accesing from the ahci driver. That simple. So it seems that in this case with an
io address upper of IO_SPACE_LIMIT we cannot do nothing but little 'hack' the code to
get the 'map_bus' callback etc from generic pci api properly working (which cleans the code a lot),
but we cannot use some of other useful and cleaner functions. I am going to send hopefully last v10
which I really expect to work applying the things I am explaining here but we should think if
this is the only way to get this properly clean and working.

See... There is no 'root bus resource [io 0xFFFFFFFF]' ... here because of my previous explanation.
