Currently, the Aspeed machines allocate a ram container region in
which the machine ram region is mapped. See commit ad1a978218
("aspeed: add a RAM memory region container"). An extra region is
mapped after ram in the ram container to catch invalid access done by
FW. That's how FW determines the size of ram. See commit ebe31c0a8e
("aspeed: add a max_ram_size property to the memory controller").
Let's move all the logic under the SoC where it should be. It will
also ease the work on multi SoC support.

xen_piix_pci_write_config_client() is implemented in the xen sub tree and

The only user of xen_set_pci_link_route() is
xen_piix_pci_write_config_client() which implements PIIX-specific logic in
the xen namespace. This makes xen-hvm depend on PIIX which could be
avoided if xen_piix_pci_write_config_client() was implemented in PIIX. In
order to do this, xen_set_pci_link_route() needs to be stubbable which
this patch addresses.
