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.
