sysbus_mmio_map maps devices into "get_system_memory()".
With the new SoC memory attribute, we want to make sure that each device is
mapped into the SoC memory.
In single SoC machines, the SoC memory is the same as "get_system_memory()",
but in multi SoC machines it will be different.

Currently, the Aspeed machines allocate a ram container region in
which the machine ram region is mapped. See commit ad1a9782186d
("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 ebe31c0a8ef7
("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
uses PIIX constants internally, thus creating a direct dependency on
PIIX. Now that xen_set_pci_link_route() is stubbable, the logic of
xen_piix_pci_write_config_client() can be moved to PIIX which resolves
the dependency.

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.
