soc/amd/common/data_fabric: add support for extended MMIO addresses
The Genoa SoC supports MMIO addresses larger than 48 bits. Since the MMIO base and limit registers in the data fabric only contain bits 16 to 47 of the MMIO address, the MMIO address extension register is introduced on some SoCs like Genoa. This additional register contains the upper bits of the MMIO base and limit. Since it's not available on all SoCs, introduce the SOC_AMD_COMMON_BLOCK_DATA_FABRIC_EXTENDED_MMIO Kconfig option to select the correct data_fabric_get_mmio_base_size implementation to be added to the build.
