soc/amd/phoenix/chip.h: add DDI configuration for openSIL
In the FSP case, the DDI descriptors aren't part of the devicetree and are instead retrieved in romstage by calling the mainboard's mainboard_get_dxio_ddi_descriptors function which allows updating the descriptors during romstage where the devicetree is static. In the openSIL case, the DDI configuration is first needed in ramstage, so we can put this info into the devicetree and update it if needed in ramstage.
