soc/amd/stoneyridge: add chipset devicetrees

Add chipset devicetrees for Stoneyridge and Carrizo, which is also
supported by the Stoneyridge code, but has more external PCIe ports and
devices. The mainboard's devicetrees will be changed to use the aliases
defined in the chipset devicetree in follow-up patches. This is a
preparation to statically assign the ops for the internal devices
statically in the SoC devicetree instead of dynamically adding them in
ramstage.

BKDG #55072 Rev 3.04 was used to check the PCI devices and functions and
the MMIO addresses.
